I still have the last half of the show to check out - Stopped after Sandler's song before bed last night, figured that was a good way to split it for now.
But yeah, echoing some other remarks, I was surprised by how much Sabrina Carpenter there was. I'm a fan, but she's not exactly someone with huge pipes that you absolutely know will stand the test of time. She's not even the best "hey there youngsters" artist they've had on the most or that gave the best performance recently - Olivia Rodrigo has already done the show twice, and "All-American bench" was pretty memorable! Billie Eilish probably would have been better if you still wanted to go young, and she would have paired better with Paul Simon.
Lawrence Welk is completely forked out. Is there some contingent that loves this skit or something? Just doing another "Goulet Sings!" infomercial with guest stars would have been better.
All of the Update bits were pretty good to great for me. Not coincidentally, I bet that's the part of the show that had the best writing.
I haven't seen the Zapruder film breakdown of the audience members, to track who was there and who wasn't, but I'm definitely curious about that. I'm not surprised that Chevy Chase didn't get an on-camera speaking role, because he's a huge brick that everyone hates, whether you're talking about SNL, his movie career or even late roles like Community. Aykroyd has kind of receded from public life except for occasional Ghostbusters work, so I wasn't hugely surprised he didn't make an appearance. His daughter was at some of the events, so I don't think there's bad blood or anything.
