I agree that people are obsessed with remaking good movies, thus setting themselves up for a disappointments and embarrassments. The only option is to actually be better than the original which will be an uphill battle the film will, in all probability, fail to achieve.
No, I lied. There's another option. You can make a remake based on an original, but different enough as to claim it "source material." But even then, it better be a freaking good movie. Otherwise, you're just setting yourself up to be grilled and served to hungry movie critics and movie buffs.
