You might not think of this movie as a Christmas movie, but it does take place during the holiday season. So we're counting it.
The Guardian says, "Eastern Promises is an exciting story about hypocrisy, decency and different kinds of honour, and about the dark underside of globalisation and multiculturalism." Slate praises it and closes with this: "If you saw A History of Violence, you know Mortensen can fuck up a guy something fierce, but till you've seen him do it buck naked and covered in mob tattoos, you haven't lived."
Roger Ebert gives it 4 out of 4 stars, and -calling the casting "pitch-perfect"- says, "The actors and the characters merge and form a reality above and apart from the story, and the result is a film that takes us beyond crime and London and the Russian mafia and into the mystifying realms of human nature." Rotten Tomatoes has a critics score of 89%.
