Umm... forgive the 7th grade English lesson (those of you who passed middle school can skip ahead to the next post... but
be honest), but so many of you seem confused. It's called
dramatic irony. The audience knows something that the characters do not. Glinda is so daft and full of kind intentions when she puts on the cape that it makes the dramatic irony all the more powerful and the audience can revel in their exclusive knowledge even more. Irony of any kind is certainly amusing and exciting for us, and, in most cases, it's funny. This includes dramatic irony. We chuckle at this poor, optimistic girl, who doesn't realize what she is doing.
Even though some of you have seen the show a million times and have very serious thoughts about the characters, I'm sure you understand that the majority of the audience is just there for fun, most for their first time, and the show was written to provoke this kind of fun, positive reaction from them. There have been a thousand discussions about all the ways (plot, lyics, music, dialogue) in which Wicked fails to hold up after repeated viewings.
That's not to say that dramatic irony
always gets or deserves laughs. Even though most of you clearly take the show very seriously, Wicked is still a light and buttery popcorn flick of a show about brightly colored characters in a fictional enchanted kingdom. It's lite entertainment, and the audience having that extra knowledge about the meaning of the cape is fun, and we chuckle about it. More serious shows don't get or want laughs for this kind of writing. Cabaret, for example, whose dramatic irony is mostly forshadowing the rise of Nazism and a bit of the Holocaust, is more likely to inspire goosebumps than giggles.
