Front Mission 3 thing was weird, the game was good, I didn't finish it as I got it like years later on PS1 but the dialogue wasn't the best.
All the cast of FF13 besides Fang and Vanille, I actually liked them a little, well Fang at least because she didn't seem as 'emo kid' as the rest of these adults, the whole thing was a bit messy.
Star Ocean 4, all of them, that game hurts. The dialogue and sounds just ruined it.
Ryder from ME:A, basically a flat slate character with no personality.
Less cringe/just because they were bad but because the situation was messed up: By the end I did not like Joel, from Last of Us and because of Col Walker, I now disassociate myself with characters in games completely, I guess Spec Ops did it's job.
