1. Least Favorite Charaters in Your Most Favorite Series and 2. vise versa

Well as far as characters I disliked in some of my favorite series, one that sticks out is Kenpachi in Bleach. I've never liked him, everyone always goes "WHAT?!" ... He's not my style...
I should also include Suzaku from Code Geass...but then again, I disliked quite a few characters from that series, even though I liked the series itself. Suzaku is just the main point of hatred.

On the flip side, I liked the Lust (Laura Bailey, Laura Bailey) character from FMA...the rest of the villains just left me disappoint. Specially that Gluttony thing.
