I watched this at my wife's behest, and I'm glad she convinced me to try it out. It's a great ride from start to finish. Far better than I expected, frankly. We watched in Black & White and I really enjoyed it. Cage really delivered in this role and the rest of the cast is great.
I do wish they had kept the original B&W shots rather than the reshoots they did to make a color version, but I guess they figured they'd lose a lot of the audience who wouldn't be willing to give a B&W show a chance these days. It is what it is, and the fact that it got made at all makes me happy.
The really nice thing? You don't need to know anything or have watched any other shows to enjoy it. It's not trying to pitch other projects. It doesn't even end with sequel bait (though the door isn't closed). You can just come in blind and enjoy a self-contained, complete story. That's so refreshing these days.
