I have just started a rewatch of Misfits (high fives Lochjessmonster) and it's still utter class.
The ratio of brilliant lines per episode is off the scale (mostly Nathan's, who is one of the best characters EVER).
Also wish I was a first timer for Dexter, at least the first five seasons. The ending of the whole thing though, is one of the greatest disappointments of my life.
Also agree with Breaking Bad.
Travelers (with Eric McCormac from Will and Grace) on Netflix is REALLY good and then two seasons in, they lost the funding and I am GUTTED.
