I think this is a really excellent little short. Great acting from the three kids. Funny, characterful, but not too over the top. It's very well scripted with some nice surprises. I love some of the long tracking shots, particularly the scene in the loo, and also the final shot, both must have required loads of rehearsal, and the timing is flawless. I also really like the grading and colour saturation which gives it a kind of old retro 70's feel adding to the whole gangster satire look.
My only concern is that some of the accents are so strong that a US audience might not be able to follow it at all, but hey that's their loss! Top short overall.
