I don't understand why some people have rated this movie as bad just because its scientifically incorrect... isn't that the point of some movies? To explore the idea of 'what if' a theory was true. Amongst the genres listed next to the movie it says Science Fiction which quite literally is a Fictional movie about Science. I personally loved this film, there could definitely be some tweaks I'm not saying that its perfect. But overall it isn't at all a bad movie.
