The Town http://www.imdb.com/title/tt0840361/
Set in the Charlestown neighborhood of Boston. About a group of guys who rob armored cars and banks. After a bank job they end up taking a hostage as insurance for their getaway, then release her unharmed. But as they aren't sure how much she knows to tell the cops, they decide to keep an eye on her. And Affleck's character falls for her and starts dating her.
Has a good character roster, good story, decent gunbattles and car chases. Sortof reminded me of "Heat" on some levels.
Directed by, and starring, Ben Affleck. Now I really was impressed by Affleck's directing of Gone Baby Gone, so I overcame my aversion to watching BA act to see this one. Glad I did. Suprisingly in most of his scenes he didn't look like he was acting - they seemed genuine. And this one was well directed as well, so good job Ben.
Definitely worth watching if you like gun battle-ey crime dramas. Worth watching if you liked "Heat". And if you haven't seen Heat - rent that too.
