Yay, I finally got a chance to watch this one.
The synop: aliens arrive in a London hood and a gang of youth decide to defend their block. I liked it. It has a great pace and is an overall cute film. The aliens are very unconventional but still interesting well actually the blue teeth is the only cool feature. Go see it if you haven't seen it yet. I know I am super late but I know it had a limited release so I'm sure it is still under the radar for some.
