Not long into "Land of the Lost," there's a joke about a monkey-man grabbing a woman's breast (the first of many), a sign the movie itself is a little lost.
The movie is meant to be a time-warp yarn about a hybrid dimension where past and present co-exist, fertile ground for an imaginative comedy, tailor-made for out post-modern, mash-up culture.
The gags, though, are about molestation, drug trips, dirty words and dinosaur poop. And urine.
Pixar, it ain't.
How long you last will depend on your taste for Will Ferrell, who stars here as a crackpot scientist who invents a subatomic particle machine (a less refined version than exists in "Angels and Demons") that sucks him into another dimension, along with a fellow scientist (Anna Friel) and a hijacked redneck (Danny McBride).
