Jack Black and Michael Cera play two cavemen who go on a big adventure in Harold Ramis' comedy "Year One," and here is what the Web's critics have to say (read my review here):

• Joblo's Jenna Bush: "The film has very little narrative, and what there is seems to be dumped half way through."

• Cinematical's Jeffrey M. Anderson: "Black is a good reason why most of this works."

• CinemaBlend's Josh Tyler: "'Year One' has no point, no purpose really other than stick Jack Black and Michael Cera in loincloths so they can wander around in front of the camera."

• Latino Review's Ron Henriques: "I absolutely can not recommend this film, but I felt a little sad because it had some potential."

• Brad Brevet at RopeOfSilicon: "Ramis racked up the talent to give this story a run, but it never got out of the starting gate."

• Matt Goldberg at Collider: "Without any memorable humor, story, or characters, 'Year One' is a pointless endeavor and offers us nothing we haven’t seen or heard somewhere else before."
