Re Marvel/Super Heros: Start with Arrow, watch 2 or 3 seasons, then shut it off. The rest (of the other shows and the remainder of Arrow's seasons) have been a waste of my time... And I'm a comic/superhero fan.

Westworld is solid because it's something new (haven't seen season 2 yet). Blacklist I'm just watching now, and it's getting slower/less interesting in season 5 or 6?

How did Game of Thrones get passed over??

Sherlock - with Bennedict Cumberbatch. You won't regret it. Each show is basically a movie (approx 1h 15m each). Start here, then GoT, then Westworld, and Arrow if you get bored / run thru all of the others.
