It is pretty funny, some cracking one liners in it, also has some jumpy moments in it as well, and a couple of grim moments, but overall its just good fun.
But it totally non stop, if it isn't the Aliens chasing the gang is some psychotic gangster, and if it ain't any of them it's the cops!
But I have to say I do love the monsters in it they are very original and its excellent film making, I am really looking forward to more of Joe Cornishes films in the future.
