There is nothing ambitious or fancy here; it is a simple early 90s teen comedy. Two high school nerds uncover a prehistoric caveman trapped in a block of ice while digging a pool in their suburban backyard. They try to preserve him in ice, but he melts and is now alive in Southern Californian in the year 1992. The two friends decide to pose him as a foreign exchange student and enroll him in high school. The concept is deliciously absurd. From here, the plot dissolves, and it loses its way. Sean Astin is fine as an actor, but his character is whiny and a little hard to warm up to. Polly Shore works in this application because he is a supporting character, which moderates his goofy antics. Early in the movie this duo of Shore and Astin does not work that well, you begin to wonder how these characters are even friends. Brenden Frazer, however, is completely lovable as the surprisingly gentle and very silly Neanderthal. His energy and childlike enthusiasm make it fun, even if the movie has no diction and very little structure. Perplexingly, the movie ends very abruptly, as if there is more to the story, but it just stops without wrapping up the loose ends. Picking this movie up now is like uncovering an artifact from the MTV generation in 1992. It seems dated, but in many ways, that is part of the charm. It is not a well-made movie, but it is still a fun watch and is worth the time for a simple laugh.
