I saw it earlier in the week and I gotta say I liked it too! I thought it was better and funnier than American Pie 2 and less preachier than the first. It seemed to have discarded the view that there needs to be a moral message so much.
Stifler was of course excellently characterised and a funny guy (with hidden talents!) then there was Jim!
I think most of my fave characters were there (Michelle, Jim, his dad, Finch, Stifler). I laughed a lot while watching it, in second sequels the jokes have sometimes gone stale but they did a pretty good job with this movie
Jim's Dad: Son, step away from the animal...
