Saw this today, great first 40 minutes but it kind of slows down a lot after that and never really recovers, plus you get a bit of behaviour outside of the estabished characters story arc to keep it interesting.
No real A listers so the acting isnt the strongest and Kate Winslet cannot do westernised russian at all, although she does cool.
6.5 for me and definetly a film you dont need to see at the cinema.
