I have only just discovered Shameless on Virgin's TV On Demand. I've become addicted this week and all I've watched are episodes from the 1st series. They are brilliant! I love them.
I've noticed that the new series starts on Monday but I really want to watch all the others first if I can manage to get hold of them (although aren't there 7?? Might take me some time!!!). At the moment only series 1 is available. I'm hoping that they put series 2 on there soon or I might end up ahving to buy the DVDs!
