I felt it was pretty lacking, it was my favourite of the pre-Avengers movies because I love the mythos but it just seemed really....eh. The music didn't match some of the scenes, some of it was pretty cheesy (when he helps Jane make breakfast for everyone, the music just ruins the scene), the action is too CGI-reliant and un-inventive. The best action scenes in the movie are undeniably those between Thor and Loki, the two add a lot of gravitas to the scene that isn't really present elsewhere. To be fair, the new one looks like this won't be the case.
