The new season on Netflix will hopefully be at least 10 episode long so I might actually take another spin at it, waiting 10 years for another 3 episodes of Luther or Sherlock is bad enough I'm not going through this again.
With US TV shows I usually wait until at least the mid season or the 9 episode pickup because lately US TV shows especially from the bigger networks have less job security than the offspring of JRR Martin novels and the Walking Dead characters.
So far we had quite a "decent" year, 12 Monkeys has been renewed, Childhoods End and Westworld are coming, the CW actually managed to make comic book shows (never was a huge comic fan, infact i never had a chance to read a single book i think) cool, we are bloody getting The Man in the High Castle show on Amazon and Marvel's Netflix production is in full gear.
The Christmas special in particular was pretty mind bending.
