I don't watch movies like that for the realism. Watching action movies entertains me because unrealistic scenes are.....well.....entertaining.
It's good to get out of reality from time time and simply enjoy what you're watching without giving it much thought.
We have similar thoughts. We become like a critic of the movies without getting paid when we take the movies too seriously. Fictional movies are made because we usually can't do or see those things in real life.
