It's worth a watch. Colin Farrell and Hugh Grant are excellent. In fact, I think it might have been Grant's finest acting moment since he told the cops the prostitute fell into his car as he was driving. The scenes with Farrell in the take away and the gangsters trying to get mobile phones off of street urchins are brilliant.
It also has Michelle Dockery in who plays a very fine gangster's wife.
I'll try and catch a couple of episodes of the series over the weekend.
