It’s useful, sometimes, to look to children, especially when they’re still too young to know how they should feel about socially coded issues like this. A number of years ago, when I was writing a book about watching classic films with kids, I sat my younger daughter down with “The Nutty Professor” — the original 1963 version with Jerry Lewis. The movie’s a neurotic blat of Technicolor slapstick that’s both idiotic and very funny, and the centerpiece is the transformation scene, where the nerd chemist turns into the suave Buddy Love. The scary music, odd angles, and weird teeth freaked my daughter out so completely she made me fast-forward through to the next bit, and at the end of the movie, she shrugged and said the movie was just OK.
