Let me save you some time and just tell you that Land of the Lost is best as a movie trailer. You've probably seen most of the funny parts on all the commercials over the last several months. I'm a Will Ferrell fan, but Danny McBride made me laugh more during this movie. There were some funny moments but overall it was a negative experience.
It's rated PG-13 and is extremely heavy in the crude humor department. I was surprised to see a notice posted by the movie management indicating that despite the rating they felt it was not appropriate for kids. I would have to agree that this is definitely not a kid or family movie.
I'll be the first to admit that the 70's TV show was not a masterpiece but it is better than this movie. Any fans of the original series will be disappointed. I'm glad I had free movie passes to it and didn't spend any money on it. I give it 5.6 stars and just hope for better when the inevitable Sigmund and the Sea Monsters movie comes out in the future.
