What I found disappointing about the finale (other than Charlie)
1. We didn't get to see the original set one last time. When Chuck Lorre said the finale was going to honor both eras of the show, I was expecting to see the original set in some capacity.
2. Jake had a very small role. I think he should've stuck around for the rest of the episode.
3. No explanation as to where the hell Louis was. You'd think Alan and Walden would be concerned about their child when there's a deranged killer on the loose.
4. No appearance or mention of HERB.
