And Tom Bosley's speech at the very end, despite the treacly music, is kind of sweet and simple; it's about the characters but it's also about the pleasure we get from following the lives of TV characters -- something that becomes explicit when he breaks the fourth wall and thanks us for "being part of our family." It's almost enough to make you forgive them for Pinky Tuscadero, Ted McGinley, Crystal Bernard, Mork, the shark jump and various incarnations of Linda Purl. Not quite enough, but almost.
Also, it's only after watching this scene for a second time that you start to ask an important question about the speech: "Two children?" "Both of our children?" What happened to Chuck? Well, Tom Bosley asked the same question in a famous outtake from this scene, where he says "Chuck? Where's Chuck?"
Any other shows you can think of that had better series finales than you might have expected?
