"Wow... what a dumb review. In fact I've just read all the three -ve reviews on tomatometer. What kind of dumb reviews are these (one of them is so funny, it's a one line review that significantly brought down the rating. I think it's one of the most significant sci-fi films ever made. The plot has several holes. But so what? It's a terrific premise, and extraordinary execution. It took watching the sequels about three times to finally get the hang of them (initially I thought the sequels were messed up). All in all, great movie. I think some reviewers live in their own world (pun intended)."
