My personal ranking for this season:
Hang the DJ
USS Callister
Black Museum
Crocodile
Arkangel
Metalhead
Overall I thought the season was not as great as the last Netflix season but still very well done. Some episodes felt a little similar like Arkangel and The Entire History of You. And metalhead felt like a total filler episode, nothing special about that one.
Another excellent season. I loved most of the character interactions. New team ups especially Dustin and Steve are the best. I feel like 008 was a waste. Having another with powers and only use them to have Eleven realize she has to go home didn't seem like a good use of someone with powers. Maybe 8 will make her way to Hawkins soon. Also Billy and Max were kinda not used. Max was alright but she seems like a love interest and Billy was just the racist trying to stop here sister. Hopefully they will have more to do next season.
This is one of the best seasons of tv ever. Everything from the writing to the acting to the music have been stellar. This show knows how to get your emotions going. I'm so glad season 3 is coming and we will get some sort of ending.
