Superstore NBC Promotional Graphic

“Superstore” return, 8 p.m., NBC.

At times, this show is merely kinda-good, in a stop-and-start, hit-and-miss way. But it soars whenever the entire cast is thrown into the break room; weird and funny ideas start ricocheting around wildly.

Now it tops that with a management academy, where things can get even loopier. Amy, smart and diligent, is there, burdened by Cheyenne as her presentation partner; the result is often hilarious. Back at the store, Mateo is an inept activist and Dina and Garrett inadvertently start a child-care service.
