Don't really want to slate this as it tries really hard.
Kept me up til 1am and I still rated it a 6.
Low budget (tried a bit hard to be higher budget) sci-fi with just enough to make you want to see it through.
Music was a bit over the top in places, the actor that played the little kid (although small part) is going places, watch this space.
Trailer made it look much better than it was unfortunately. 6/10 seems fair.
