Matt Waring’s review published on Letterboxd:
I think I would have enjoyed this a lot more had it not been for the fact that the main characters, the heroes of the story, violently mug someone right at the start of the film. It makes it pretty difficult to side with them after that. Especially considering they don't really seem to show any remorse or give any viable reason as to why they were doing that in the first place. I mean, I know aliens are attacking you and that, but at least say sorry to that woman that you threatened at knife point.
Aside from that, this was decent enough. A pretty refreshing, different take on the whole 'alien invasion' thing, and it did raise a good point about how seriously the police/general public would take a threat like this if it was happening in the middle of a dodgy council estate. However, it does suffer in the same places that a lot of 'horror-comedies' do, in that it isn't scary enough for the 'horror', and it's not consistently funny enough for the 'comedy'.
That said, that lad's 'Granny Magnet' t-shirt was brilliant.
