Saw some interesting ones in the past few days:
A Simple Plan (1998), directed by Sam Raimi - a minor masterpiece
Carnage (2011), directed by Roman Polanski - amusing and very believable behaviour of four "adults"
Heist (2001), directed by David Mamet - with an evil Danny DeVito and a dependable Gene Hackman
and Haywire (2011), directed by Steven Soderbergh; I am now a little smitten by martial arts star Gina Carano.
