This time of the year:
Game of Thrones (HBO)
Penny Dreadful (Showtime)
Preacher...just started, excellent
Arrow/Flash just wrapped up the season
Mr Robot...seems like season 2 should be coming soon
The Last Ship starting up very soon
Otherwise, I watch a ton of fishing and car shows, not to mention grilling/cooking shows. Love the Outdoor channel and Velocity.
Then there's youtube where I've got a good list of well done channels that put out quality content.
