Hi there. I'm just some nobody, I wrote the original Homestuck diatribe on the old site a few years ago. At the time it was partially satirical, my views on the webcomic have evolved since then, but so has the comic. I cannot say whether Homestuck is good, or bad. It's Homestuck, comparable to itself. Homestuck is, complex.
Let me jump the gun and say that's one of the principle reasons this site should not review it. Here are just the facts, Homestuck is 10,000 pages long with over 800,000 words. Half that is contained in one part (Act 6 Part 3). It's got almost 5 hours of Flash footage. It's gone on for 7 years and taken an entire team (Art team, music team, ect) of dozens of people to create, with one author leading the helm, a computer programmer with an ecclectic, bohemian sense of humor. It's the fastest updating webcomic to date (19 year break), on some rare days it updates dozens of times to 50 pages in a day. It has over 26 albums worth of music published, many tracks utilized within. It spans references of every topic imaginable, has well over a 100 characters, is a story told across multiple timelines, universes, in an one-linear narrative from different formats and media utilities. It is hella complicated.
Speaking real quickly, I used to really love it initially, the first read going in always struck me as nostaligic in my experience. Not knowing what to expect, going in for the first time and learning about Sbub, the Trolls, all the characters and settings, everything else, it was a myraide of experiences. Novel as hell, spastic and high-octane for pushing the boundaries of a web-medium, Homestuck is a radically unique experience that cannot be summed up accurately by any amount of recollection or laconic summary. As far as things go, my honeymoon phase with it is long over and I'm past the nostaligia. I cannot appreciate it in that pure wonder sense anymore, but I can certainly appreciate everything that it is and has tried to do. It means a lot to me, as has the fandom and entire community around it. Do you know how much fanmusic has been made around it, or fan adventures dedicated to it? You all know that fanfiction exists, well how about fan-comics for a single work of fiction? In it's entirety, to undergo reading Homestuck is Homeric beyond compare.
I'm rambling a bit, my feelings about it aside, my original point stands, that all of it is beyond reviewing meaningfully for the scope of this website. I've already heard griping and complaining about the page length earlier in the thread, even giving into the absurd notion that you could split up the reading among a group of people. This already highlights the biggest problem with any proposed reviewal here. If you want to seem like less of an idiot in the face of anyone who'd take you seriously, you really have to abandonded that attitude. This, as pretentious as you'll think it to say, is just like someone said earlier. You just won't get it. In matters of enjoyment this isn't a problem, you can just not read it and move on, if it's not you cup of tea. In terms of analysis and critique, what's a more surefire way to fail in your criticism than not understanding the material? If you aren't even willing to read it you have no leg in this race.
And that's not the full problem, that's the bare minimum of preventing idioticy ensuring a dumb review. There's so much beyond a surface reading even a group would need approach with a fully academic mindset to tap into, less they give said dumb review. One where you won't convince fans, critics or anyone with forethought about the comic. Let me speak at large about the fandom, the way posters described them earlier surely amounted to their estimation as idiots. Or whatever falls under the 'obnoxious fandom' groupthink that will say 'You just don't get it.' You're talking about a group of people that have been meticiously following a hypertext fo 7 years and thinking you can talk down and critique such a work? That you could have anything meaningfully to say about it? Homestuck isn't just complicated, it's monolithic. It has callbacks upon callbacks and eats literary tropes for breakfast. It breaks narrative conventions with savvy regard for it's storytelling. It's aware of itself and it's fandom and the fandom are aware of it and they're both aware that it's aware. The entire experience thrives on near-masturbatory levels of penetration into it's own depths. There are so many references and sublties that would fly right past you, it'd be like a bunch of elementary schoolers attempting to decode and find flaws in Multivariable Advanced Calculus equations. Cannot punk that shit bro. Not knowing this comic and what Homestuck truly is will undermine you completely.
I've already heard supposed criticisms in this thread. The art looks lazy because it copy pastes the same model? There's a reason for that. The artist is actually pretty competent at art (Or used to be, at one point), but you wouldn't know that. The trolls seem like annoying deviant OCs? There's a reason for that too. The Alpha trolls are copy-pastas? The first 3 acts are too long? Yata yata doesn't make sense? For literally everything one could point out, there's a more comprehensive understanding and justification for, which has been discussed to death and back and touched upon by the author, scrutinized by the fans, and then argued back and forth for ages. These 'footnotes' aren't necessary for reading and enjoying the comic, but for actually understanding and reviewing it, they're imperative to make any meaningful statements. Trust me on this. The majority of critisms that could be put forth by some half-baked imbelcile trying to read 'one act alone as part of a group', would be so low level they'd be made fun of in the comic. And those fans that say you just 'don't get it'? They're scathingly critical of Homestuck and it's flaws and many contentiously, even bitterly so. Do you really think you could beat a 7 year headstart from the droves of geeks on /co/ and Reddit? They're so immersed in tearing apart the comic, even moronic theorizers and self-proclaimed scholars like BKEW are savagely shit on for their daft rationalizations. Do you think any review about a furry webcomic or vidya-bro image-story could suffice, or anything similarly vacuous? What do you expect to say about this work that hasn't been said by the author and fans already?
TL;DR, it's too much for you. If you haven't read it yet and don't intend to read it or have to resort to splitting a group up to read acts, give up right now and forever already.
If you really really want to get in the review game for this sicknasty piece of trash, my advice would be to go back and start with Problem Sleuth. Read it slowly, enjoy it, and work your way up to Homestuck. Then take some time, a lot of time to comb through Homestuck. Take it slow, use whatever forums and age-old discussion were available, Have a friend or friendly guide to help you out and explain things to you. Read up a lot in it, go through all of Hussie's old formspring, reddit and tumblr [email protected]'s (They're achived around the net), read his annotations, actually ask a group some questions and take it all in comprehensively. (But don't ask /HSG/. They've discussed it to death and transcended Homestuck entirely. It's like babby wizard apprentice trying to seek console from the dark-robed eldergods speaking in eldritch tongues).
Alternatively gather whoever has read it here, beginning to end here and try to form a more structured, intelligent and fully articulated opinion. And remember the scope of what you're tackling with here. You're still walking on thin ice, but atleast you'll have some skates to stand on.
That's my take on Homestuck and the whole Reviewing it dealio.
H3Y B4DW3BCOM1CS, 1S TH1S YOU????
And yes, the ending was ambigious. Ambigiously awful, but I won't get into that. Read it for yourself and come to you own conclusions.
