I was also let down by Twin Peaks: The Return.
What worked about the original iteration of Twin Peaks was that it was a mash-up of a police procedural and a prime time soap opera sprinkled with a generous amount of oddness and surrealism.
Where The Return failed for me was it pushed the soap opera part into the background, and it felt like a lot of the characters got the short end of the stick (Audrey in particular). In a lot of ways, these characters were the heart of the series, and with most of them only making cameos, left the series cold.
I also wasn’t a fan of Dougie, which ate up a lot of screen time and felt like a joke that went on for too long. The new characters, especially the brothers who owned the casino, didn’t feel particularly well integrated into the narrative.
Too many deceased actors. I think that Don Davis’ absence was well integrated into the story, but the way BOB and Phillip Jeffries were integrated into the narrative didn’t really work. The constant use of stock footage of BOB in particular just served to remind me that Frank Silva was dead.
I also would have liked to have seen Hawk get a promotion to sheriff instead of shoehorning Truman’s brother in.
