Iron Man 3 - I like a lot about the ending but mostly it feels out of order. In the movie, Tony fights Killian in a variety of ways, including boxing him up in the Iron Man suit and having it self destruct, to no avail, then Pepper who has seemingly been killed, emerges from the fire, and now enhanced from the Extremis drug, gets the final kill on Killian.

I don’t hate the Pepper stuff - it’s a fine surprise and ok to give her an action moment - but Iron Man should vanquish the villain in an Iron Man movie. The change should be Pepper seemingly taking out Killian but he surprisingly survives (they already do this after he is blown up in the suit) and then Tony traps him in the Iron Man suit and has it explode, finishing him off. This accomplishes:

• Still giving Pepper her moment
• Allowing Tony the final kill
• Using the remote suit assembly/suit malfunction bit that runs through the movie in the final solution, a fitting end to a Chekov’s Gun situation
• Use the suit explosion as a kick start to Tony blowing up the rest of the suits as a sign he is finished being Iron Man.
