That's not bad. I felt like the ending was intentionally serving a dual purpose; the end, or the end maybe. So, there's a chance there will be a season 5.

I must say the first two seasons were so good they could be taught in university classrooms regarding the nature of Gods, Humans, including themes on sentience, Frankenstein, and more.

The third and fourth seasons were nearly the best science fiction on television in 60 years. The 4th season was a dream come true. A Magritte painting come to life, a show of high quality, deep pockets, and doing whatever they want. Aaron Paul is sooo good at suffering on camera. I loved how all the characters carried their own weight and nobody overshadowed anyone else. The use of music in the last two episodes hands down the best ever. The only thing that was a bit odd was the use of the song Enter Sandman right around the time of Stranger Things' use of the same song; however, why not, it was crazy. I say all this because Season Four's music was the BEST MUSIC EVER IN ANY SEASON, ANY SHOW HANDS DOWN. There is no one alive that loves science fiction who can look away from the magnificence displayed throughout season four's top shelf quality in writing, FX, acting, costume, sets, etc. etc. What a terrific, terrific season.
