Either Mean Girls or Come From Away.
I was skeptical when I heard they were making a musical out of Mean Girls. However, when I saw it last year (and have since seen it many more times) I was pleasantly surprised. The cast is amazing, the music catchy and clever.
Come From Away has become my go-to recommendation for anyone. It's a no-intermission show, but more than that, it finds a way to balance the importance of the seriousness of what happened on 9/11 in Gander while still being entertaining, funny, and makes you really think about how a community came together when a nation was in trouble and needed it the most. You can't go wrong with either one, honestly.
