I saw this today and I liked it.
Some people walked out but I suspect that they may have gone in expecting something a little more Guy Ritchie-esque and east end hard man than the theatrical, other worldly hyper-reality that this exists in.
I've read that it fits in the Clockwork Orange mode of unreality and I'd certainly agree. Not just because of the music.

It's dark and it's violent and it's funny and 'gritty' but it's more like some wild artistic caricature than the usual cinematic biopic.
