Basically list the top 3 anime you hated, regardless of their popularity. I know I'm gonig to bring in some butthurt. OVAs count as well.
Sword Art Online- Lame characters, rip off of .hack (one of my favorite franchises of all time), the marriage thing was...ugh.
Bleach- Just can't stand it. It was far longer than it needed to be and I just hate it.
Gundam Seed- Ruined Gundam for me.
Special shout out to One Piece. To me it's just dumb.
