I'll go with Attack on Titan for this one. I had a lot of friends tell me to watch it, and the Internet wouldn't shut up about it,so I tried watching a bit of it. Never again. Not since I got sick of Bleach have I wished so hard for a mainstream pile of garbage to fade out of existence. I get how some people might like it for the action scenes and whatnot, but I need my "deep story lines and characters" (that people rave about) to have a bit more depth than a kiddie pool.
