I definitely do.
I'll watch the first episode of a anime and end up never coming back to it even if I liked it a whole lot. The only way I'm able to avoid doing that is if I watch it with friends or something and even then I sometimes postpone watching the last few episodes for awhile.
I think a lot of us can be annoyed by things like that sometimes. XD
Out of the main characters Kid is my favorite but my overall favorite is either Crona or Stein.
It took me a bit to find it but here. This thing I found while randomly browsing Tumblr made me want to avoid the series. You can skim through it if you want to.
I've heard good things about it from some friends but have kind of been avoiding watching it since the creator's background made me very uncomfortable and turned me completely off to the show.
(It's probably pretty funny though since people keep talking about it.)
