New York Times:
The movie is, nonetheless, of a certain fascination in its joining of two styles: pot and advertising.
Despite obviously dated aspects like clumsy psychedelic effects and some turgid slapstick sequences, the film is still remarkably vital and entertaining.
The clean-cut kids and the created kinetics work up a 'so-what' reaction too soon in the 85-minute stretch seques from war to westerns to desert chases to mad scientist brushes in the Columbia lot.
