Is Black Mirror Good?

The first 3 seasons were great (except for maybe 1 or 2 episodes). Each episode is usually revolved around technology and it tries to make a point (how technology might harm us / affect us). And also each episode features different scenarios, characters, etc. I binged all the seasons on Netflix and 4th season goes downhill. Maybe because they try to please a bigger audience. So I would only recommend watching the first 3 seasons if you are short on time.
