Pacing is a little slow, and some of the characters can be a bit much. Otherwise, some of the characters are likeable, and whilst the plot is uninspired, it still moves along fairly quickly.
If you have seen something like Bleach or Naruto, you will probably like it because it really is better than both of them.
However, if you never liked shounen, stay away - you may want to watch the first episode for the awesome fight either way. The animation and art is generally very good.
Soul Eater is not for everyone, but it's an easy watch either way. Plus, I heard that the BONES have decided to speed up the pacing soon.
I can only say it depends on your tastes.
