They just stretch these superhero movies too much! Round up a trilogy and end with up. The Iron Man movies were pretty solid (at least the 1st) and if the 3rd will be great too, it's gonna be perfect!
Under normal circumstances I'd agree with you, but what you're forgetting is that it's not only about the IM movies but about the MCU as a whole. Tony Stark will propably appear in Avengers 2 and 3 and maybe the sequels of Cap, Thor, the Black Panther and Dr. Strange movies and wherever he is needed (depending on the script and/or if the movie makers decide to put a Tony Stark cameo in their movies).
Therefor it is an issue WHO will play that role.
I think a change of actors would work if it happens in Avengers 2 and will be addressed similiar to how they addressed the recast of Rhodey in IM2. This will get the new actor the acceptance of the fanbase and MIGHT lead to a second IM trilogy
