Little tip for creators of musical comedy shows: if you're going to set your show in a specific era with a specific sound and tone, it's probably not a good idea to have all your music sound modern and like nothing from the era you're trying to recreate. This was exactly the mistake Elvis made, when Baz Luhrmann decided to include hip hop music in the scenes with African Americans.
From the very beginning, the show took me right out of the 50s when they updated the classing Grease theme song to sound like a generic, modern, boring hip hop song, rather than the 50s sound they gave us in the movie. You know why the movie Grease was a hit and is now considered a beloved classic? Because they did make all the songs Disco. I'm not sure this show has any kind of lasting power when right off the bat it forgets the era it's trying to recreate.
And yet it's trying to copy the movie because so many of the characters from this show are reminiscent of characters from the movie. It's so busy trying to emulate the movie (except the music) that it doesn't bother to give itself its own identity - unless they're trying that with the bad music, in which case I have to wonder who this is for. Few fans of the original movie are going to want to hear the songs done in a modern hip hop style. Are todays millennials going to be interested in a prequel to a movie that came out decades before they were born?
While some of the characters are interesting, I'm just not sure this is a show that will (or maybe even should) make it.
