I just finished watching Breaking Bad, which I resisted purely on the grounds everyone else was going on about it being brilliant...and I must say, that it is. A lot of US tends to be kinda daft. (Coughs) CSI (Coughs)
The other best American TV show in my opinion was Southland. A cop show where the cops behaved like cops. No bullet-proof vests designed to show off an actresses' boobs. No super tight shirts to show off an actor's muscles. No, they wore genuine LAPD uniforms with real cops and reformed gangsters as extras and supporting actors.
If I'm being honest it got a little wonky towards the end but their wonky was still pretty damn good.
