Reboot is a new show that chronicles the revival of a sitcom called Step Right Up. Shenanigans, I assume, ensue. (Shenanigans sort of already did: Leslie Bibb and Michael McKean were cast originally, then replaced by Judy Greer and Paul Reiser.) From what I can tell by the first three titles, every episode is named after a sitcom, which is amusing. I hope it’s good; I’ve missed Rachel Bloom on my TV, and the idea of her with the great Judy Greer is very enticing.
