As a comedy, "Mannequin" is completely lacking in wit. Its idea of humor is having a gay character drive a pink car with license plates that read "Bad Girl". All its secondary characters and physical gags are painfully stupid and unfunny. But as a fairy tale and a romance it fares better. As a fairy tale, because it has an initial idea that is easy to relate to (everyone has, at one point or another, looked at a doll that seemed strangely lifelike), and as a romance, because Andrew McCarthy is a likable enough hero, and Kim Cattrall brings a combination of innocence and unmistakable sensuousness to her part; you'd never guess that she is actually six years older than McCarthy!
