True Detective and Penny Dreadful are my tippermost toppermost favourites. Very richly told stories I can go back to and find new things in.
Game of Thrones, The Walking Dead, The X-Files are sometimes brilliant and often enjoyably watchable. I like the worlds they exist in, even if what goes on in them isn't always up to snuff.
The Simpsons (up to about season 10), Futurama and Father Ted keep me amused.
Of late I've been watching In Treatment. A very interesting idea done well.
Sherlock up until the third season was really enjoyable (about 4 3/4 very good episodes out of six). The third season, and the recent one-off, I've found terrible, such that they've kind of soured the earlier stuff for me. I now get my Holmes kick with Elementary.
On that note, there was also a series by the name of 'Murder Rooms' from the early noughts starring the (now sadly gone) Ian Richardson as Conan Doyle's medical lecturer (and inspiration for Holmes' deductive powers) Dr Joseph Bell. He and Doyle (in a Holmes-Watson dynamic) investigate mysteries based on the Holmes stories. I suppose it's a Sherlock Holmes origin story. I think there was one 2 hour pilot episode, and four 90 minute episodes.
Most recently I was absolutely bowled over by Gravity Falls.
