Review by DaCritic-2

I had pretty low expectations when I first saw this movie. I then found it hilariously funny. Some of the humor is a little juvenile, but the "caveman" language (developed by Ringo Starr himself ... I think he claimed once on the Tonight Show that his favorite word was "zug-zug," which meant "having sex") was great; also an amusing scene where the cavemen who speak this language meet a caveman who speaks English and tries to teach it to them.

Not to mention dumb dinosaurs, a humungous mosquito, Atouk's (Ringo Starr) pile of unappreciated inventions, and Lana's (Bach) come-uppance at the end.

Good, mindless fun.
