I would have given this film 4.5 stars but I will give it five rather than four, simply because it was a spectacular movie. Sure, its not perfect, there are a couple of plot holes and the film could have been slower in places. There are a few cliches and some of the acting could have been better. That said, I really enjoyed this movie. The scenery and cinematography is breath taking, I loved the props, costumes, visual effects and the subject matter. If you are a sci fi fan and/or a model/prop maker then I'm sure you will really enjoy the film. It may also be one of the films that is better the second time around, I hope to see it again.
