My favorite part was when Scooby and Shaggy found a mummy in the actor's closet. I liked the character of the ogre because he was sneaky and could swing on the ropes without making the curtain close.
I think this ogre is like Shrek, the ogre because they both scare people and both are mean. Shrek changed by the end of the story but the opera ogre stayed mean throughout the book.
I have read other books by the same author and they are all similar because the villan is always in a costume like a ghostly gorilla and a howling wolfman.
I recommend this book for first through third grades for those who like adventure books that are exciting to read.
