Here I'll try my best to rank the (in)famous Black Mirror episodes with as little bias from other sites as possible. This is my opinion after some weeks or months of watching, not directly after. Do not read if you don't want spoilers.

General comments: I like the episodes from Netflix better in terms of actors and production. The dull,  British acting can get annoying to me sometimes. But overall all episodes have something interesting and dystopian to them and can be greatly discussed afterwards in regards to technology, philosophy, psychology, biology, society, ethics, morals, humanity etc. One of my favourite shows ever.

S1
E1 "The National Anthem" 3/5 Most unrealistic episode, probably, even though it's almost not even a Black Mirror episode in its style. Filthy plot to begin the show with, but yet overall kind of dull. Very funny and ironic that no one went out on the street to see that the princess had escaped.
E2 "Fifteen Million Merits" 2/5 Alright plot but kind of unrealistic and still sort of boring
E3 "The Entire History of You" 3,8/5 Very well made and great plot line. I can see people getting these incorporated into their eyes in the future (I sometimes wish that I had these!).

S2
E1 "Be Right Back" 3,7/5 I think I've seen this plot somewhere else. Very freaky episode when she unboxes her dead boyfriend.
E2 "White Bear" 3,7/5 This episode looks bad at first sight, like a bad horror movie, but then only gets very interesting at the end. That plot twist turned everything on its head. Reminds me of the classical death penalty/torture/rehabilitation discussion.
E3 "The Waldo Moment"
E4-ish "White Christmas" 5/5 Wow, what an amazing episode. Three different small stories packed into plot twist after plot twist and great technological ideas. The tech guide is very plausible, the cookie scares me a lot but the worst part is the "blocked" function. People would not get a chance to defend themselves!

S3
E1 "Nosedive" 5/5 Brilliant episode and so so relevant today with all our social media. We started out with this episode and I recommend others do as well. It's both fun and creepy and interesting. China is working on the same system! 
E2 "Playtest" 3/5 I didn't really care for this episode, but I love the way we don't know what is in his head and what is the game. Really trippy. Don't watch it on drugs.
E3 "Shut Up and Dance" 4/5 An episode about punishing "bad people" in a Saw kind of way, almost. Very sadistic and entertaining. As always, Black Mirror plays with your emotions and makes you root for the bad guy.
E4 "San Junipero"
E5 "Men Against Fire"
E6 "Hated in the Nation"

S4
E1 "Crocodile"
E2 "Arkangel"
E3 "Hang the DJ"
E4 "USS Callister"
E5 "Metalhead"
E6 "Black Museum"
