Deadfall is a truly awful film. That being said, it's everything I ever wanted and more!
I'm gonna be honest here, I watched this purely for the purpose of seeing Nicolas Cage go batshit insane, and I was not disappointed. But while I enjoyed the film, that doesn't mean it was good. I'm not joking when I say the acting here (outside of Cage) is utterly horrific. The lead guy is a smug wooden plank, and everyone around him is some form or another of a pathetic cliche. The "grim noir" tone of the plot is laughable (in some cases it actually makes the film unintentionally entertaining), and the lack of thought put into it is mind-boggling.
Because of the flaws, I can't give the film anything higher than a 2/10. But don't get me wrong, if you're in the mood for some "so-bad-it's-good" fun, this is the movie for you!
