Should you see Cry Baby?
Yes.
If you are interested in musicals you cannot only see the great-fab-brill-terrific-or-even-just-good-ones. Playwright-Director Moss Hart said, "No one learns anything from a hit." In order to sense what might work, you have to see your fair share of what doesn't work and then you have to figure out why it didn't work.
After you see Cry Baby (and it is on TDF) discuss with your friends what you liked and why, and then what you didn't like and why.
And believe me, everyone's taste is different. I'd rather see Cry Baby ten more times then even think about last season's production of Company that a lot of people loved, and it won a Tony.
"If my life weren't funny, it would just be true. And that would be unacceptable."
