Why the low ratings??
This movie isn't a 4.6. It's a low budget sci-fi movie and I can completly understand why people could hate films like this but how about not watching it then?? It's not like they are trying to trick you into thinking this is the newest Michael Bay Movie where the film reel is just a tied together line of money. Compared to big studio movies the effects are outdated, there is no denying that.
If you are someone who can enjoy low budget movies and are a fan of the "Lost in space" sort of movies, then this is a guaranteed evening of entertainment.
