I'm sick of hearing films being trashed simply because they happen to star an actor more known for muscle mass than theatrical prowess. If the later was the only measure of quality, Laurence Olivier's movies would have all been financial blockbusters. Yes, I'm referring to Jean-Claude Van Damme. In some cases we're doubly Dammed when he goes back in time and meets himself. After all, this is a science fiction film.
Time travel is the central plot device and it is used very well throughout the story.
Luckily the screenwriters were a little more grounded in reality. Why trouble our grandparents when we could make a quick buck. Which is were the main villain comes in. Senator Aaron McComb wants to be the president but his less than charming personality would, under normal circumstances, preclude any chance of election. But all he really needs is enormous piles of cash in order to buy sufficient air-time to sway the mindless masses.
