I wish it either focused more on the characters of the show, i.e. the kids like Ben and Emma, the guest stars, other people who should have shown up like they did with Mr. Heckles (I loved when he showed up).
Or I was hoping they would have done a show about where all characters are in 2021 (seeing their answers as they were acted out not by them describing it as they did when James Corbin asked where they saw their characters now).
I love Friends but The One with the Reunion left me very sad. I expected more after 17 years of waiting.
