Interesting point about Tony and Pepper's conversation at the beginning! I was too caught up in the content to think about the dream part being significant. Might be a red herring, but still intriguing. ETA: You know, I actually think this points towards the fact that Tony's vision from AoU and his worst nightmares in the wake of New York actually came true in this very movie.

I didn't mind the Tony and Strange interactions, I thought they had a lovely little arc in this - I mean, Tony didn't actually know Strange at all before this and to suddenly be confronted with his worst nightmare and to have this slightly arrogant guy who deals in magic of all things? He's certainly going to be on the defensive for a bit. But I loved that they had actual discussions about plans, that somewhere in the middle, Tony told him very clearly "I've had this guy in my head for six years, this is my plan [to confront Thanos on his own planet to keep him away from earth], but I'm not sure it's the best one, what do you think?" That was great and exactly the kind of thing I wanted from Tony.

And Tony's new suit was awesome indeed, loved the use of nano-technology.
