I don't care about ratings. For me, there are only two classes of modules on CPAN: "modules that solve the problem I needs to fix in a reasonable way" and those that don't. A module M1 that is stable, lightning fast, beautifully formatted, documented in perfect prose, has and has tons of features is less useful to me than module M2 that has no documentation, a clunky interface and horrible code if M2 solves a problem I have, and M1 solves a problem I don't need to be solved.
