Oh my god, it's finally releasing in the US! (I've been holding in my glee.) Pretty much had the exact same reaction as you (except I missed the Sheriff, shame on me :P I had worried about the bots, going in, on top of the above. I had religiously avoided trailers and spoilers leading up o it, though, and did not realize AIM was such a large part ^^;; but all the plotlines were very delicately and well intertwined, and I appreciated that.

Please let Pepper keep Extremis indeed! It also seemed rather openended as to whether Tony gave himself the fixed version later, but that might be just my pet theory. I see it again for a third time tomorrow, and may be taking notes. (For cosplay purposes. >.>)
