"Junior", the story of a man who becomes pregnant, is a flimsy, one-joke comedy. The sole joke is Arnold Schwarzenegger, in the role of the male mommy, acting out every cliche of pregnancy by becoming feminine and losing control of his emotions. How well you like the film depends on how often you can find humor in the role reversal.
"Junior" is such a by-the-numbers production that I hesitate to even call it a comedy. And with Danny Devito as a gynecologist, the film almost qualifies as a horror flick. Oscar-winner Emma Thompson, in the role of a clumsy scientist who falls in love with Arnie, is as splendid as always. Director Ivan Reitman, who has created such successful comedies as "Ghostbusters" and "Dave", milks the premise for every conceivable laugh but fails to deliver more than the occasional chuckle. This would be fine if it weren't the same chuckle over and over, but alas it is.
