The first half is a mind-numbingly stupid, nonsensical boring filler, that could be presented as a written narrative in about 50 words. The 2nd half ties it in and is quite good. However I fell asleep 3 or 4 times in the first half because it went nowhere and wasn't entertaining. This deserves two scores, one of -5 and one of 7, so overall from me it gets 2/10.
I love scifi/fantasy, thrillers, dramas and even horror. I have watched loads of B and C movies that I have enjoyed. This just couldn't make up enough ground with me to get a thumbs up, the first bit went on too much with little content.
