While I was thrilled to see McCarthy's return as Spicer, the skit copied too many of the funniest jokes from the prior week, so it didn't work that well for me. Ironically though, the highlight for me was the upgraded podium.
I also think there should have been other questions addressed before Spicer finally settled on problem-child/rival 'Glen', for pacing reasons. They just jumped right in to Spicer's digs at him and it gave us nothing to contrast it with until the later, less interesting press interactions took place.
I also found McKinnon's bit near the end of the skit forced, and dare I say unwelcome.
Here's to hoping Spicer gives them more to work with in the coming days.
Oh, and Weekend Update, such terrible deliveries all around, my god.
