The Twilight Zone based in technology rather than Sci fi.

That's basically the best way to describe this amazing show. It can be dark, it can be heavy, but more often than not it's very compelling and worth watching.

I will say, since this is an anthology, that some episodes will be very different than others. Due to a person's personal taste their favorite/not so favorite episodes may vary dramatically. One of my personal favorites is the second episode, Fifteen Million Merits, yet often times I've seen it in the lower half of people's lists...and that's ok. Each episode will speak to someone in a different way. It's part of the fun.

As long as you can handle thoughtful stories that don't always have a happy ending, you won't be disappointed by this series.
