The commercial for this movie features our heroes (the visiting Martian and his earthling friend) in the midst of a car chase. The Martian (Christopher Lloyd) shrinks the car, which goes into the sewer system and comes up in a toilet. We get the toilet-eye view just as a hugely overweight man is pulling down his pants to sit. This is a good indication of the movie’s subject matter and humor level.
It is also a good indication of the failures of the rating system. It is hard to imagine an appropriate age group for this movie, but because the language is euphemistic, it gets only a PG rating. As with Flubber, Disney has remade a familiar story with souped-up special effects, but with a poor script. Not recommended.
