Query: Slow and disappointing

This is yet another science fiction film that begins with a good story idea, but drops the ball. It took at least 40 minutes for anything to happen and when it appeared there might be some action the movie ended. If you want to see a good science fiction movie watch Splice, because Monsters doesn't make the cut. Why do so many film makers think aliens look like squids or reptiles?
