The Thirteenth Floor has an amazing premise and some great ideas. Shame that it's also mired by terrible dialogue, B-movie plotting, and a cheap looking production. Blending elements of Dark City and The Matrix though never achieving the greatness of either of those magnificent works of sci-fi, I would still recommend The Thirteenth Floor for what it sets out to do. It's also cool to see the younger versions of Gretchen Mol, Vincent D'Onofrio, and Dennis Haysbert.
