Aw disagree completely, I reall enjoyed
Attack the Block! Thought the chemistry between the kids worked well, and had a cool boys own adventure type feel - like an urban
Goonies 
I don't think it was aiming to be an out and out comedy - a sci-fi actioner with comic touches I'd say
(but then, I haven't seen
Hot Fuzz, so maybe it's a valid comparison) . . .
