Action movies and super-hero movies are really just modern-day interpretations of mythology. The ancient Greeks had their Apollo and Odysseus, while we've got Indiana Jones and whoever Liam Neeson is supposed to be. The audience really doesn't expect the same rules to apply to gods as apply to men.
That being said, I'm with you on disliking these movies. I find it too difficult to identify with characters that don't face the same consequences for their actions as we do. If I wanted to hear stories about gods and magical creatures, I'd go to church!
That is an interesting thought!!
