I love Doug Judy enough that I'd forgive this episode any myriad of sins. And it's definitely not sin-less.
Cons:
I'm glad that Holt is back to being the Captain, but I will freely admit my frustration that his demotion wasn't more of a plot point this season. It didn't lead to any meaningful character growth, and because Terry just took over for him, we didn't even get the excitement of a new character to shift the group dynamics. Also, given what a big deal it's supposed to be that Holt is finally back, why was this moment relegated to a subplot, where nobody but Terry and Rosa seemed to care?
The other subplot was honestly one they could have deleted entirely from the episode and I wouldn't care. Amy is in charge of picking out a new vending machine now that a broken outlet has been fixed. Predictably, Scully and Hitchcock have lots of opinions about this, and equally predictably, Boyle tries to go for some fancy weird one that only serves fish balls. In the end, the machine Scully and Hitchcock choose is installed, but it shorts out the lights because the voltage is too high, so everything returns to normal by the end of the episode. My prevailing emotion watching all of this was just kind of a general... shrug.
