One of those movies you hesitate to say you like for fear of cinematic snob ridicule. Too bad. What’s not to like about a movie starring Jack Nicholson and a bunch of irascible martians who shoot down a proffered peace dove to embark on mayhem. Even amidst all the death ray disintegrations, the movie is excruciatingly funny. So pt your high brow pretentious aside, sit back and enjoy watching an interplanetary slugfest.
