From Cracked:
We don't ask a lot from our movies. A nice story, maybe with some sex, violence and Batman thrown in.
But sometimes a movie comes along and takes on special meaning because it's based on a true story, and so we watch with rapt attention knowing that some real dude lived through all the awesomeness on screen. But if you're going to go with the "Based On A True Story" tag, all we ask is that you make the stories sort of, you know, true. You can do that, right?
Not if these movies are any indication.
