Agree. Sometimes it costs nothing to make things more believable without having to give up any artistic license or even far-fetchedness. Makes for a much better movie. My favorite example of this nonsense basically ruining a movie was "A Beautiful Mind". If you ever read the book, the truth was much more compelling than the fictional garbage represented in the movie.

On the other hand, another far-fetched loony movie that was actually well-thought out enough that it could be "believable" was "21". Completely contrived idea, but all the elements such that it could be true in our existing reality were in place.

In this latest one, as they were driving all over town with the money, the basic question "why didn't they just fly the money by helicopter from the vault to the hijackers?" arose in my mind. It was very funny when Mayor Gandolfini asked why didn't they just fly it there, and when Denzel went out to ride the helicopter to deliver the money, somebody says "finally some sense here" or something like that.
