This movie is a mess. The writers shamelessly stole ideas from several sci-fi movies and concepts and then threw in a heavy dose of mechs & Groundhog Day! The cardboard characters, lack of plausibility and lack of chemistry between the protagonists are bad enough. To top it all off the cartoonish rendering of the aliens (Ghost Busters?) are designed to scare and be believable to a 4 year old. As an adult it is hard to buy into. Fell asleep on the first viewing. Upon rewatching I found I did not miss much.
