It's a law of the universe that comedies set in prehistoric times are doomed to fail. Wholly Moses anyone? History of the World: Part I? Clan of the Cave Bear?Actually, I take that back - there is one good comedy with a prehistoric setting: Buster Keaton's The Three Ages. Alas, Jack Black is not Buster Keaton, and neither is Michael Cera. Their movie Year One looks unspeakably dreadful, nothing like one of Keaton's graceful, inventive comedies. And I actually kind of like Jack Black. Michael Cera I can take or leave. Looking on the bright side: at least there's no Daryl Hannah. I don't think.
