The effects in the movie are good and the idea is good but OMG what a dragged out waste of nearly 3 hours. I implore you don't waste your time on this drivel. It only gets 3/10 for the effects. The stars in this movie should be ashamed of themselves for making a movie just for the cash. Horrible just Horrible. The movie has a poor start and you have to work out what is going on for yourself. Once you understand the premise of what they are trying to achieve then it does make some sense. They head off on a tangent that is hard to follow and there are many disjointed segways in the movie. the best way to watch this movie is on a system that you can rewind so that you can go back and try and figure out what is going on. Oh and it's one of those movies that people mumble in and the sounds effects are way louder than the talking, so you will be reaching for the remote allot.
