I don't know why everyone dislikes UU. I think UU is great. I imagine as she gets more screentime she'll jump up in the troll rankings significantly, but I already like her more than Feferi, Sollux, Eridan, and maybe even Vriska. UU's conversations tend to be pretty enlightening and I like her gimmick of being, like, the "Homestuck fanbase" troll where she draws ridiculous fanart of all the characters.
