Dexter is one of my favourite shows too. I need to check which seasons i haven't watched all of. I think i watched the first 3 or 4 and some episodes from the later ones. I've watched a few episodes of true blood when it was on tv but not seen the whole of any seasons. I have the universal channel and sci fi channel so I have seen a bit Ghost whisperer as well. It's ok but not one of my favourites.
