Well, one advantage of not being raised on Musical Theatre is that even the classics are new to you. I only know of "Guys and Dolls" from pop-culture parodies. As such, I expected it to be a little dated, especially in its humor. It wasn't. Apparently, Relationship Humor is timeless.
This particular production's most impressive element is the sheer size of the cast. It makes for some real "showstoppers." It really is a complex undertaking. I almost missed this show, and I am so glad I didn't, you shouldn't, either.
