These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Uncanny Valley: There is one adaptation of Peter and the Wolf (the one narrated by Sting) where a number of characters in the first and third acts ("Peter and the Wolf" and "March in B Flat Major", respectively) are played by puppets. The animal puppets used for the bird, duck, wolf◊, etc. are odd-looking enough as it is, but the puppets used for the humans (such as the narrator◊ and the conductor◊) are... downright terrifying.
