It doesn't give you that much info yet, except that Guy Pierce is now the kind of sleazy suit Sam Rockwell was in the last one and a first closer look at Ben Kingsley as the Mandarin (which looks cool).

I like that it seems most scenes are from the first act, that's IM getting his ass kicked and house destroyed while coping with the events from The Avengers. It's interesting that he does not just shrug away the fact that he flew a bomb through a wormhole.

But yeah, decent trailer with some space left to enhance. That's a good thing.
