Trying to keep a long post short:
Need some short anime series, 30 episodes or less, that has some pretty good action but isn't totally retarded. I'm not picky, but my friends would hate something like Azumanga Daioh and prefer something like Naruto (which I hate) or Bleach (which I got tired of).
Already being considered:
Elfen Lied is already ruled out so it doesn't need to be suggested, but it's also an anime we like.
