What adaptation for a movie was bad?

If any adaptations stand out as uncalled for, I would pick most of the Disney animated features. Jungle Book is so good as a fun kids movie, I don't think Ruyard Kipling is rolling in his grave, he even wrote for kids. But, the movies that sweeten tales that were designed to be dark and told with a powerful moral, Disney never fails to through the baby out with the bathwater. The Grimm Brothers tales, having sold the most copies of any book, second only to the Bible, and are likely rolling in their graves. Maybe, they could charge Disney with deformation of character, or characters so to speak. But, the nineties was the worst decade for Disney, putting songs in the least appropriate places. If they want to do musicals, they should just buy up Broadway, or better yet build more theaters, or better still rehab the great show houses and movie houses of the rust belt and support the live stage. But, they most certainly must not make animated movies into some kind of bastard combo of public domain works and crappy music, plus imposed family values that dirty the originals. It teaches the very kids it caters to, with it silly stories, that the bottom line is all that maters.
