This is a slapdash comedy that?s too toothless to be satire and too dumb to be witty. Jack Black and Michael Cera play a pair of banished cavemen who stroll through various episodes from the Old Testament, like Cain and Abel and a circumcision-crazed Abraham, before settling in for a wild time at Sodom. This uninspired riff on the Bible rarely lands any laughs. The comedic aim of the film is extremely low; the scatological humor consists of farting peasants, bestiality, eating poop, urinating on your face, genital mutilation, and lots and lots of pedophilic jokes thanks to a grotesque, lispy Oliver Platt. Year One (of what exactly?) is a big step back for co-writer/director Harold Ramis and a general waste of everyone’s time and talent. Black and Cera do have an interesting and playful ying-yang chemistry but they have so little to do given the rambling, episodic nature of the plot. The characters make anachronistic pop culture references or talk in self-aware circles, the celebrity cameos do little, and the jokes lack any lasting momentum. Somewhere Ramis wants to make statements about religion and faith but the flick is too timid to do anything, so the movie limps to a finish with its lame “be your own chosen one” message. This is a prehistoric comedy with rocks in its head.
