Common Sense Note
Parents need to know that there are spooky, dark scenes more suited to a Scooby-Doo cartoon, plus loads of slapstick cartoon violence. There are also racy scenes in which a lead female dances for a room full of hot-blooded males who whistle and go gaga over her.
Sexual
Content
Considering the audience, some of the material is iffy. The only female character sings a song that mentions her bosom (not once, but twice.) She dances in a fashion that shows her underwear, and she undresses in silhouette behind a screen in front of Tom, Jerry, Sherlock Holmes, and Watson.
Violence
Slapstick cartoon violence in every scene can be jarring, though pretty typical of Tom and Jerry cartoons: forks in rear ends, items swallowed so that the character looks like the shovel, coin, mailbox, etc... A stack of bricks is dropped on Tom's head so that he comes out looking like a brick, tails set on fire, perilous falls from great heights. Lots of bonks on the head, doors slammed in faces, and so on. There is even a scene where a character promises a "rendez-vous with pain" and proceeds to beat the offender off camera.
Language
"Bosom."
Social
Behavior
This cat and mouse team fight with intensity, though it is to be expected, since that's what they've always done. However, the treatment of the only female in the cast as a love object is rather unexpected. Granted, females have been whistled at in cartoons before, but this character dances a suggestive dance, showing her bloomers and singing about her bosom. Since when does Sherlock Holmes cavort with showgirls? Why should he start now?
Consumerism
