Fun, but ultimately forgettable. I wish there had been a little less punning and plot twists, and a little more character development. Great satirizing of mystery fiction, though, and the nursery rhyme thing (diluted weirdly with bits of Greek mythology, fairytales, and other fictional razzmatazz . . . what the fuck is a Jellyman, anyway? Am I missing a reference?) was very fun, even if it is a bit hard to swallow that Humpty Dumpty could have bedded all those women. Though, I suppose that's the point.
All in all, completely absurd, but missing a stable backbone to hold it up.
