I fucking hate gen 4 with a burning passion (by which I mean DPPt, I'm not including HGSS). I think Sinnoh is a very ugly region, traversing through it was a pain and I'm not saying only move wise, I mean visually as well, it's UGLY. The dex is filled with the most disgusting pieces of shit I've ever seen (until gen 8, at least), they're all so fucking ugly I greatly struggled building a team because I didn't want to see them all the time while fighting. The music is forgettable and bland, and the human characters except very few have horrendous design. That Ronald McDonald looking motherfucker, Marley, Fantina, fucking Thorton, pretty much everyone. The legendaries suck ass, Dialga is ugly and Palkia looks like a fucking dick, Giratina is only slightly better but still look 2edgy4me. Arceus is good, I'll give you that. Heatran is ugly, Shaymin is ugly, jesus fucking christ. There isn't a single thing I like about this godawful game, even the gameplay was insufferable and the least fun I've ever had with Pokemon ever, I had more fun with SM, and I fucking hated the gameplay of those as well. To me gen 4 is an absolute disgrace, it's objectively shit, there's nothing good about it, maybe only Cynthia since I'll admit she's a good champion, but other than that gen 4 can suck my ass, I fucking hate gen 4 and the constant Sinnohfetuses circlejerk going on here, bunch of fucking autists reeeeing at even the slight criticism instead of trying to argue it calmly. Other genfags when faced with hate threads will try to argue and explain why they disagree, but Sinnohfetuses will just "BUT M-MUH PEAK, MUH COMFY, I BEAT YOU'RE JUST A JEALOUS GENJOHOENOVALOLAFAG" fuck off, comfy my ass. Try to speak and argue like actual human being instead of going into a pissy fit when someone dares shit talk your c-c-c-comfy. Also Dawn and Lucas look like shit as well, god, everything about gen 4 is ugly and horrible and I'll never like that abomination of a gen.
