Hi
I watched the movie on Sunday, I loved the AC DC track and the Stark Expo as seen in the trailers etc.
The normal techy error exist as with all the comic movies.
Less jokes than the first movie.
But without spoiling anything from the movie. Its good for a sequel, but as normal I think the first was better. Its all linking and building nicely to the 'Avengers' movie, so watch for the hints, and as normal Stan Lee

However stay until the very end of the credits its got the normal teaser for more good things to come.
Enjoy the movie, and look forward to dicussing it with anyone on the forum.
