The Chaos Experiment, Directed by Philippe Martinez, 2009
If a movie is merely not good, I can turn it off or, at the very least, keep it on in the background. However, once a movie goes beyond that and becomes actively bad, something happens to me. I become transfixed in a Medussa's gaze of ugly cinematography and jaunty acting, unable to do anything but watch the train crash. And few trains I've seen this year have crashed as hard as The Chaos Experiment (my full review here).
It starts out okay, but once the viewer is taken inside the titular experiment the whole movie derails. Val Kilmer and Armand Assante are on the periphery of everything interesting, weaving in and out of the pain that is the majority of the movie. It's poorly lit and shot like the cinematographer just got done staring into the sun. Plus the ending is an abysmal slap in the face to anyone who suspended their sensibilities long enough to actually watch the whole thing. Can't recommend it to anyone.
