As a kid I always used to play with my rulers in school. I used to bend them then back, bend more then back, kind of to see how much I can bend it. I always snapped them in the end. That's how it feels to me. I really liked the 1st season. 2nd season I enjoyed, plenty of times I was like, ah no, this is gonna go off the rails, but then they stopped juuuuuuuuuust before. This finale snapped it for me.
Not only did we get the fanboy-jerking mirror of the R1 Vader scene, in the end barely anything of real consequence happened in this series, there were hardly any stakes at the climax, no sacrafice and a character from outside the series stole the show. I really liked the first season because it kept itself to its own story and characters. As said before, this series was a vehicle to set up 4 new series.
I'd also like to meet the person who stepped away from the monitor looking at the CGI Luke and said "yup that looks good". I have mad respect for Doctor Sleep for not going down this route and I can't understand why didn't they cast Charles Dance in R1 as Tarkin with some minor facial prosthetics.
Ah well, was fun while it lasted.
