I am aware that dialogue should not be the only aspect of a film to be considered in evaluation. However, I was responding to the poster who had written, "I think it comes down to whether or not quips are important to you. If they are, then you wil consider IM 3 a well written film."
For instance: Batman Begins has a great script, a near perfect cast (except for Holmes, who drained the vitality of every scene she was in,)and some nice action sequences (I love the dock raid.) However, Goyer's dialogue rams up the cheese factor to irritating levels, with lines such as "I gotta get me one of those." I can see why people like them, but I find them to be cheesy, and in excess in the film. A more problematic line happens with the people who were watching the water mains: the audience knows(and is seeing) what is happening; there was no reason to include them in the script, let alone cutaway to them, when the screentime could have been used better.
Thus, a good film is compromised by the cheesy dialogue. Compared to Man of Steel, however, the dialogue in BB sounds like it was written by Tom Stoppard.
