So I'm watching it and quite enjoying it. It's finding its balance as the season progresses. The acting is getting better - and it was a solid C+ to start with, unlike the Netflix series "Shadow Hunters" that has (yet) to overcome the acting.
The shows I'm interested in right now seem to have a BSG+[concept] vibe to them. The Magicians is BSG in tone, but Harry Potter in concept. The 100 is BSG tone as well, with something like Red Dawn as the concept? I'm not sure, really. Just sayin'.
I do like the machinations and the willingness to eviscerate characters that one might think important. I haven't read the books or looked at the publication timeline, so I don't know how they relate to GRRMDeath.
