good bad movie adaptations

[yendi]

So, I've been thinking about movie adaptations. Most suck on all sorts of levels. And most of these also take major liberties with the adaptation. I'm not just talking about cutting a few scenes, or shifting the importance of characters slightly. I'm talking full-scale,major plot changes (the novel Forrest Gump begins with a line along the lines of, "My mama used to say, 'Life is nothing like a box of chocolates,'" and continues to diverge, and we won't even mention The Lawnmower Man).

But every once in a while, a movie comes along that, technically, may be a terrible adaptation, but manages to be a great movie in its own right. Blade Runner and The Shining come to mind. Anyone have any personal favorite movies that are, technically, terrible adapations?
