It's a great movie. although there are a few pot holes that i just can't get over with. But i do recommend it . Give it a try and I'm sure you'll like it. Now regarding the pot hole that i mentioned about ..........
( SPOILER ALERT )
During the murder in the hotel , how come no one look into the recording as to who passed the slip under the door and who shot Sergei. Its 21st century , there has to be a camera around there . In the flashback we can clearly see that Juan did not put on any mask. SO had they simply looked into the recording the whole murder would have been solved in a flash.
