High-concept, short-lived sci-fi experiment with a Matrix-y slant: aliens have been on Earth for the last sixty years and maintain their invisibility with the help of the U.S. government. Most of what we consider history were just alien experiments, and now a covert group of heroes get to jaunt about recent history while trying to undo the alien’s plans. Pretty silly stuff, but sci-fi fans could do a lot worse. Plus it’s got JT Walsh in it, and that’s always a good thing.
