The equation has never been more accurate than in the brilliant Czech surrealist's newest film, "Little Otik," based upon a classic fairy tale of an infertile couple who adopt a tree stump as their baby. It quickly grows into an all-devouring monster that eats the cat and then the postman. Locked in the basement, Otik becomes a favorite of Alzbetka, a creepily precocious little girl, who is otherwise engaged in reading books on sexual dysfunction and warding off an octogenarian pedophile.
