I saw The Guard yesterday - very enjoyable. It has one of the ten standard plots (mismatched characters having to co-operate), and the story is mostly pretty straightforward, but the dialogue is great if you don't mind a lot of swearing. There are a few unexpected twists, but nothing like the ones in In Bruges (written and directed by the brother of The Guard's writer-director).
Good acting all round, too. It's very much Brendan Gleeson's film, with Don Cheadle at one point disappearing for some time. I wasn't entirely clear whether the ending was happy or unhappy, but maybe I missed something.
The cinema was unusually full and there were a lot of guffaws (many of them from me).
