A perfect example how mixed a series can be. Black Mirror is a series about how technology will change our future. Every episode is independent and from a different director.

I recommend watching season one, two and four, but not season three and five.

The first two seasons where the good starting of the producers, but when Netflix bought the series, there came season three. And that season was ... just bad. The story's where very bad.

Then Netflix made season four and that one is my favorite. The following season five was not good. Not as bad as season three but not really worth to watch.
