The film is actually not that bad. If you can get past the gangsta aspect it's worth a watch. The aliens are really well done for a UK film with such a restricted budget. I was pretty impressed with a few scenes. It reminded me of Aliens at points but suffered from that thing that all UK films seem to have to be lighthearted at points and jovial in attitude even though it's an alien invasion.
Where's my cake, Bedelia?
