Chappelle monologue was good, better than I expected (and if we're comparing similar-ish types of material/approaches, much better than the Bill Burr monologue from earlier in the season). The only big "blah" moment was the "maybe women should make less" joke, as there really wasn't much of a joke there, just more of a statement intended to illicit a reaction that isn't a laugh, which Chappelle probably knew was gonna happen, so, why put it in there at all?
The MO for SNL as of late is if a stand-up comic is hosting, they basically let them do a bit of their act for their opener (Burr did almost 8, Mulaney did almost 10). It's lazy, as when you combine that with the much-longer cold opens they do now, there's not as much time left for actual sketch comedy, but if you're not producing quality material somewhat consistently, maybe that's not a bad thing.
