See it if you like smart lyrics, catchy melodies and small shows that are charming
Don't see it if you need big production value or don't like shows about children
See it if you want a purely fun musical, featuring adults playing "nerdy" high schoolers. The songs are full of great puns. Overall a good time.
Don't see it if you don't like nasal-y voices, a bunch of the cast has them. you don't want to hear people spelling.
