Breaking Bad Prison Break The Killing was also really good (USA Version)
True detective S1 was amazing (probably my favourite crime season ever) looking forward to watching S2, Matthew Mcconaughey is the perfect part/amazing in it
Trailer Park Boys puts me in stitches. I am also a big fan of cartoons, like Regular Show and Adventure time, oh and Gravity Falls o_O Those shows may be made for kids but the humour is quality, its like they expected older people to watch them.
The older series of Grey's anatomy were truly phenomenal. Up until season 7/8, that show really rocked. Its lost its touch a bit now, aside from a good ending last season was mediocre, and this season isn't that great anymore
Big bang theory never fails to make me laugh, supernatural is another firm favourite.
Despite an iffy ending, the anime Deathnote really gripped me as well, and I'm not normally big on anime.
