It seems opinions I've heard before of Homestuck are either "after Cascade is not worth reading" (Act 6 is not as good or whatever) or "retcon was bad and made no sense" but I don't really agree with either of them. The not that large percentage of Homestuck I dislike comes down to "toxic relations that either get looked over for reasons and not terrible relations being blown out of proportion for reasons" or "this certain world building thing(s) should have had more development"
At least Act 2 has a trailer. Friendsim was very good, it's quality was never "this is as good as the other works at the time" but it was also not poorly written to the point of "I don't understand anything more about this character besides what was presented beforehand." The overall opinion on Friendsim: establishment of characters was well done, and it was a good idea for what it was originally trying to do (content between act 1 and 2) but could never replace Hiveswap Act 2.
Epilogues I didn't read (oops?) but I believe i may have gotten a mostly concise picture of things that went down, so it's possible that either HS^2 is an entirely neutral outlook for me due to not reading the Epilogues or I would have felt completely neutral about the Epilogues as well (I would say the latter would most likely be true but there is no way to tell.) Pesterquest wasn't as good as Freindsim but I have a slightly more positive outlook on it than completely neutral, in some instances it did do some welcomed character backstory development (Karkat's struggles with drone patrols, why Nepeta is the only beta troll not living in a hive*... small things that may or may not have need clearing up) and the parts that most people seemed to hate, I didn't necessarily have too much of a problem with. PQ alright but without it not a lot changes without it.
Here's a definite unpopular opinion: I like Problem Sleuth
as much as Homestuck. an equal amount, not one over the other, they are both extremely well done.
