(4/8 is "Moderately Bad")
I actually think that Cyndi Lauper and Jeff Goldblum together have some solid potential for A class romantic comedy (and yes, I do think that Cyndi Lauper can be quite funny. See some of her work in the Mad About You sitcom), sadly this isn't quite the space for that.
The plot itself is wholly uninteresting- it really should've tried to stick to it's knowingly-wacky-humour angle, because the film actually has the actors that could pull it off. I suspect though that the "wackiness" arose from plain incompetence in direction and script.
I'm kind of sad that there aren't more comedy films set in a world with genuine psychic capabilities. And I'm sad that this wasn't just a film about two (perfectly matched) comical psychics. Fortunately I know of a certain pop star's music which can cheer me right up.
