Sherlock (BBC): I like how much detail they put in each episode and how you found lots of things to connect. Everytime you watch it, you could find another clue and I just love it. Furthermore, I love both Sherlock and John, they're great. Sadly there's just 3 episodes per season, and it has three seasons. (I hate to know I have to wait yet a year and a half.

)
Hannibal (NBC): This show's also /very/ good (imo, of course). But it should be taken carefully because some scenes are really strong. Anyway, very well planned.
Doctor Who: It's fun, I love everything that has to be with space and travel in time. I also feel related to the Tenth Doctor.

I love many characters, there, as I said the Tenth Doctor, Rose, Donna, The Ponds, River... LOTS.
Cosmos: As I've said, I love eveything that has to be with space and this is great. I love facts, so I love learning, and this is a fun way to do it!
They're the ones who I love the most. But I/we also watch another things, a wide range of things.
