Too many holes in the plot, at every turn a mental battle to keep telling yourself : "it's science fiction". There are a couple of web sites that go over them and I felt better about the movie after reviewing the mental gymnastics required to view the movie. The reviews were not kind but I adore scify so I enjoyed the movie and would pay to see it on the big screen again. This movie is a master piece in terms of special effects ,color,cinematography. A must see for even the casual scify movie goer. It is movie best viewed on the BIG screen.
