This movie actually starts out with some laughter as high school antics ridicule a nerd. After 10 minutes the film takes a whole different route and time period. The nerd travels back in time and encounters prehistoric cavemen and cavewomen. Instead of giant reptiles which is standard for this type of film we only see a bear and a mountain lion. Did not know that they were in the dinosaur times. When producers of a film do not want to spend any money this is what you end up with.
