I have always preferred Warner Bros. cartoons to those of Disney, and the obnoxious "Runaway Brain" is a perfect example why. I saw it shown right before Diane Keaton's "Unstrung Heroes" (about a boy in 1962 Los Angeles embracing his heritage after reconnecting with his blacklisted uncles while his mother has cancer). I doubt that the cartoon could appeal to anyone over the age of nine. It's nothing but a pointless cash grab. Disney has made some perceptive movies in the last few years - Wreck-It Ralph, Frozen, Coco - but these Mickey Mouse shorts are like a power drill in the brain. Avoid it.
