Just finished watching this movie with a friend.  We had both watched the anime previously and this is ok compared to the anime.  you get the gist of the plot line but of course having to tighten the story you lose some of the important details. Some things changed from the anime but they were not bad things, just different. The main girl was spot on with acting like the character she was portraying.

We did laugh a lot too, but that was because we have a tendency to insert dialog during the slow parts. MST style
