Unpopular opinion about the special cameo appearances.

I didn't mind Idina doing her Elphaba battle cry. I thought it was a fun little easter egg callback. Was it necessary? No but I didn't hate it.

Edit:to the people asking if it's an unpopular opinion, everywhere I've heard, people expressed they didn't like it. I've seen a lot of movie review videos of people saying it's one of the few things they didn't like about the movie. They liked the cameo but not the battle cry reference.
