Went to see this last night with my 15 year old daughter.
We both really liked it. It had just enough humour (bitter, savage humour) to make what was in essence a little 'sorta-documentary' on hideous people being hideous - the sugar to help the medicine go down.
Very good indeed, and loved Barnsley Zhukov, cracking turn by Jason Isaacs. in fact, a bloody good cast when you look at it.
