I quite enjoy the first one. Second is awful though. I have a friend who claimed that TF2 is better than TF1, I seriously considered cutting ties with him then
I think RDJ's performance as Tony Stark in IM3 is the strongest one. I agree that the tone is different. Some plot points are stupid and too convenient. But like many Shane Black movies, the dialogues and the humors work for me.
IM1 is still the best to me cause it's too special I guess, seeing your favorite character brought onscreen for the first time. It's mostly sentimental
Steve Rogers is flawed to me, but different opinions I guess. Steve is hella stubborn, doesn't listen to anyone when he thinks that he's right. That's a seriously big flaw to me.
Yeah, IM1 is still better for me. I just adore that movie so much And I doubt any solo movies will touch TA level for me either.
I agree with you about the end credit sequence, nice mash up of all three movies.
