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.

I just wanted to say how much I agree with every word of this! I just saw it again and this time it even hit me harder that despite them being confrontational Tony turns it around by laying out his reasons for not jumping right into action to get them back to earth. When he asks, "Doctor, do you concur?" that in itself is such a profound character moment. And then Strange lays out how his first duty is to protect the Infinity Stone whatever happens to Peter or Tony - and that is such an important character moment for him, and I loved how it ends with Tony basically agreeing. ("Good, moral compass.")

It's all so fraught with tension, but I think it is very strongly built around the foundations of these characters and explains why the end up working pretty well together pretty quickly - even though they're not friends.
