aye, well we know how accurate movies are to the books/comics.
the iron man movies painted tony start to be nothing more than a "genius billionaire playboy philanthropist" while the comics went through the same dark and more serious phases as batman went through.

A dueler is only a good as his finest lift.
I don't know whether or not the reason why the Iron Man movies weren't as "great" is due to the character's ability to expose the elements that the Batman did, or just due to the director's choice. From what I've seen, there can be a lot done with both, but so far, Batman has been in better movies.
then ironman shoots him with a laser. or shoots him with 50 missiles or calls in jarvice to do something, or OR flies away.
Batman can't fly. Ironman yes.
Batman is smart and can fight, but fighting against a human in a suit who stands a chance against the Hulk and Thor? I don't think so.
Now with Stark? I don't think Batman would know what he's up against. He would try Batarang, obviously ineffective, then he would try something else equally ineffective.
