As others have said, the first show of the season always sucks. (Always — I worked there 40 years ago, and it was true then.) I thought this one was less sucky than usual.
The meta-humor of the cold open worked. We chuckled.
The host did a decent monologue. (Hosts who aren’t comedians usually just tell one joke and then slide into a mini-sketch with one or more of the cast members at home base. Teller isn’t AFAIK a comedian, but he did a commendable job.) And the old home video was delightful.
The BeReal (or whatever it is) sketch was funny. The Charmin Bears sketch was not. My wife liked the dorks-in-a-bar sketch; I didn’t. As for Women of a Certain Age at a Resort … well … it existed. But as my wife said, “If you’re expecting laughs from the 12:55 sketch, there’s something wrong with you.”
As usual, the best part was Update, but even that was below par. The new kid’s bit about his parents (which I’m sure was simply part of his stand-up act reformatted to include questions/prompts from Jost) was good, but his delivery wasn’t great. I can’t blame him for being nervous in his first solo bit in his first episode, and hopefully he’ll settle in. Yang’s bit was hilarious, but only because of the over-the-top way he threw himself into it. The material was meh, but he killed it.
ETA: Forgot the texting game show. We both groaned, “Not another game show,” but it turned out to be good. Except for the inexplicable slandering of NdGT, which made no sense.
We, too, are not the audience for some of these things. Neither my wife nor I knew that the Mannings MST3K live football games (although that didn’t affect our appreciation of the sketch). Neither of us have seen the AMC video. I’d heard of BeReal, but she hadn’t. And whatever the dance that Yang and Teller did at the end of the bears sketch was, it got a huge reaction from the audience, so I assume it’s some new TikTok thing or something.
Summing up: not great but not terrible, and above-average for a season opener.
