After a lukewarm start, Superstore has generally grown on me. America Ferrera helps ground what could have been an otherwise overly wacky and absurdist take on big-chain retail, whilst the core cast of secondary characters at least feel like an unusual group of characters. Whilst it rarely detours too wildly from the kind of hand-cam sitcom that shows like The Office really popularised, the creators have at least run with the setting, providing a surprisingly diverse cast from a number of perspectives. They're also happy to break out of their own comedy stereotypes a little from time to time, with Mateo and Cheyenne, in particular, having some nice moments that allows them to be more than simply the catty gay one and the dumb young one, respectively, as the season develops.
That said, I'm not wholly sold on the whole Amy/Jonah set-up, and was happy to see the initial "love triangle" with Dina was firmly shoved to one side; her character has really begun to feel a lot more enjoyable once we got past that point. I'll give them credit for the reveal that Amy is married, though: it's an unusual twist on the standard Ross and Rachel dynamic, so I'm interested to see where it goes/how they deal, and whether it ends up bringing a slightly darker subtext to proceedings.
On a more positive note, I think the show has some really fun (and surprisingly/worryingly realistic) cutaway gags and cold opens. We're not talking Brooklyn 99 here, but still better than they need to be as quick fillers to transition between scenes. And then there's Garrett. I was initially a little unsure about the character, as they felt a little like a discount Chandler with some disability jokes sprinkled on top. However, by the season end, I'm a full convert! They've written someone who isn't just mean or uncaring or desperate to seem cool; he's more of a trickster type, a literal embodiment of the chaotic neutral personality type. Any opportunity is exploited to fuck with somebody and no one is safe, but they're totally happy for Garrett to also be emotional, vulnerable, shocked etc. It's a surprisingly fun dynamic and easily my highlight of the show.
