Hollywood's main goal is to suspend your disbelief for approximately two hours, a feat that would be unattainable if studios chose to go with honest movie titles. But like honest Disney movies, a too-honest film title ruins the magic and makes the film that much less appealing. While dishonest biopics leave out important details to improve their stories, funny honest movie titles simply shift your perception of the entire film subtly enough so the story doesn't change, but the feeling behind it does. And because real life pales in comparison to the intrigue of fiction, you get titles like Mystic River instead of "Oops, Vigilante Justice Didn't Work Here!"
The brutally honest movie titles below may not change these films plot-wise, but it ruins them thematically. Try as you might, you probably can't look at The Blind Side or Pretty Woman the same way again. Well, maybe you can, but honestly, funny honest movie titles often are more entertaining than the films themselves. Just ask Avatar.
