I'll Give You Something to Cry About - This movie is almost 30 years old now.

You know this movie was butchered beyond belief during development and Bluth (the director) hated it for years, never-mind it's infamous sequels and how everyone talks about the young voice actress's murder

Yet despite all this, rather than being forgotten or mocked like others in it's situation (off the top of my head: The The Black Cauldron and The Thief and The Cobbler come to mind), it's regarded as one of the best animated films ever made and left such a strong emotional impact on so many people who think fondly of it even well into adulthood.

God That movie. Such a great movie, and I think it was the reason I loved Dinosaurs growing up, and still enjoy them now
