It could be just because I work in education, but I am very entertained by Arnold Schwarzenegger as a kindergarten teacher. Even if the story stretches credibility, that's not why you'd watch this movie. You'd watch this movie because you get to see the unstoppable Terminator/Commando/Barbarian hobbled by a room full of 5-year olds. The film has a charming cast of supporting players that includes Pamela Reed, Linda Hunt, and the underused Penelope Ann Miller. The film was directed by Ivan Reitman, who I love the description his son (fellow director Jason Reitman) gave in a Marc Maron interview, that his dad takes stories and formulas audiences love and make them even better, while he (Jason) likes to take characters and stories that audiences hate, but then make audiences love them. My main complaint is regarding the action and police investigation portion of the story, which was certainly necessary plot point to get Arnold in a classroom, but all seems kind of out of place, particularly a climactic shootout with the ponytailed villain at the elementary school. Those action film elements are really not that interesting and awfully routine, especially when compared to the comedy, which is the brightest part of the film and is what makes it worth watching.
