I remember how much you enjoy NCIS! (me too!) Oh, yes, the Blacklist too! I unfortunately missed too many episodes last season and need to see if I can find them somewhere. It will be starting up again soon!
A few other shows I've caught by happenstance (passing through the room, channel surfing and due to sheer laziness, ended up watching 3-4 episodes in a row) that I'm not particularly proud of...Swamp People, Dog the Bounty Hunter, Bar Rescue.
