See it if you want to see theater's inner working. A play about actors at various career levels auditioning & performing as played by acting students.
Don't see it if you expect professional level performances. These are students. They work hard but they are clearly still learning.
See it if You don't mind simple staging. You like a lot of singing (it is a musical). You want to hear some funny lines. There are moments to laugh.
Don't see it if You want something with more meat and potatoes as a play. You don't like musicals. You need elaborate staging.
