The finale has finally come and gone. I thought they did nice job with wrapping things up. There were elements that were predictable but they resisted doing a bunch of cameos, keeping it to just the regular cast members. Some thought the show had lost its punch and the characters had become somewhat caricatures (especially Amy, but nowhere near as bad as Alan Harper from Two and a Half Men). That is a challenge with a long running show. Don't allow the characters grow and you're criticized for stale characters. Allow the characters to grow and you're catch it for changing things. If you really want to see how the characters changed, watch the unaired pilot of the show. I liked the tie-in from Young Sheldon showing what the various characters were doing when the young Sheldon was listening to the Nobel prize announcements. In the end it was a heartfelt expression of what the characters meant to each other.
