It was on netflix a month or so back, can't find it at all anymore. Basically it's an english crime flick. The opening scenes start off with a few doctors in a morgue examining bodies that seem to have come from a crime scene, after that there is a cellphone placed near one of the bodies, it rings and goes into voicemail and a message starts to play of someone saying they have bad news or something. And that's where I stopped watching and I never bothered going back. On the front of the cover for the movie, there was a quote or something from Quentin Tarantino saying it's one of the best movies of the year or some shit.
Did you try browsing the 2009/2010 releases on IMDB? Perhaps a cover or two may help you recall the film.
It's definately a new movie. It was on netflix on xbox for a while and they took it off. So it's from 2008-2010.
