The movie is a crime comedy with a predominantly light tone. Despite the hostage situation and criminal elements, the violence is cartoonish (stun guns, tasers) rather than threatening. The fast-paced narrative uses farcical humor to undercut tension, resulting in a happy ending with romantic resolutions.
