I've seen Redbelt three times now and conclude that it's probably my favourite of David Mamet films. That's not to say it's his best because there are some major flaws to the final act, but over all it's quite a unique film which in the way of formula is very standard of it's genre. It's a martial art film and one of the best I know of... you have the lone fighter upholding respect and all that he believes to be honour. Just about every martial arts movie uses a similar structure but Redbelt differs because the sincerity and modesty keep it firmly grounded. There's actually little fighting throughout the film but when it happens, its skilful and precise. The performances are amazing and as a breath of fresh air, Tim Allen is pretty damn good in a welcome straight role.
