Troy Patterson over at Slate is even less kind toward the show:
Our cavemen are diligent upper-middle-class consumers. Note the mentions of cognac and panini presses and caramel biscotti, and check out the scene on the squash court, and then wonder what is up at ABC. One suspects that Cavemen will be gone from the schedule soon enough, but how long will the network's zany experiments in packaging yuppie-male anxiety grind on?
The show does seem to be in keeping with Hollywood's generally jaded view of men.
