Having just gone a little cold turkey from watching the last season of weeds (season 6) on Lovefilm, I was looking for my next USA box set fix. I then found Dirty Sexy Money - totally great fun. It's basically 'Dallas meets Arthur' with the antics of completely disfunctional super rich family being plus a parallel subplot of the family lawyer trying to get to the bottom of who killed his father. The latter is pretty much irrelevant but the over the top dramatics and shenanigans is compelling entertainment.
Nip Tuck, Burn Notice (which my brother in LA works on btw), Weeds, Sex in the City, Entourage - now Dirty Sexy Money - nobody makes these glossy, sharply scripted shows as dark and delicious as the USA.
