When all's said and done, the suspense build-up and chase has been done a thousand times over but it seems to work in this movie until the last twenty minutes when I have two gripes. First, the special effects ain't all that special - that's a real let down for a film that has some well shot action scenes prior and decent suspense. Second, the most implausible action finale (which I won't relate so i don't spoil it for anyone). Surely something more probable could have been thought of? Not to mention the contradictory threat which couldn't have occurred. For what began as a decent film, it was a real shame to be let down so badly at the end.
