Clearly this show has the same writer's room as it's got that hyper-rapid insane jokes-per-minute thing that those two shows share and that makes future re-watches rewarding because you're pretty much guaranteed to have missed at least half of them.
Also - the girls are all super talented (especially Dawn), the songs are catchy as hell - there's not much to not like. I can guarantee the bad reviews here are from the folks don't like the fire hose of over-the-top surrealist pop-culture jokes being fired at you.
Renée Elise Goldsberry is doing a perfect "Jenna from 30-rock" impression in a lot of ways. It's sometimes jarring to be looking elsewhere and hear her voice and think "Jenna!" then turn around and see Renee. Maybe it's just me.
Anyway, big thumbs up from me!
