If I tell someone those things about the Obfuscated C entries, they still won't be able to tell a good one from a bad one. Different judges will rank different entries differently. Even if judges agree, it's possible that other people will think the judges wrong.

Other kinds of art are no different. Heck, most interesting things are no different. Try listing criteria to distinguish a good programming language from a bad one and see how many people you can get to agree with you.
