I'm a newer fan, so when I finished Homestuck, I let the ideas marinate for about two weeks and then dove into the epilogues. As a longtime fic writer and general fan of the "homestuck self-aggrandizing metanarrative horseshit" situation, they were fantastic. My complaints are minimal, and plenty of scenes are standout. Besides, despite carrying bias against men, the Ultimate Self is such an interesting idea that I ended up really enjoying Dirk, and it recontextualized plenty of his scenes in Homestuck to be gripping to me as well (timaeus did, in fact, Testify).

June's character in Candy is especially compelling, doubly so when drawn against Meat. She's really externalized from Earth-C, and the mounting feeling of wrongness or needing to take action against a world that is so wholly a step to the left and wrong is just gripping. I love it.

re:Berry, you kind of nailed it on the head, in a way. I can immediately understand the issue some people have with the Epilogues, but reading them, I couldn't help but feel it was the best step forward for the story, and that anything placid or afraid to do rough things to the adults who weren't fully healed by/after Sburb would've been far, far worse.

I even like Yiffany Longstocking Lalonde-Harley. I know that's not technically an Epilogues thing, but the spirit of it is there.
