- Crosses the Line Twice: The movie turns the ending (in which Vic and Blood eat Quilla) into this, capping it off with the title song (an upbeat country tune) and the main duo laughing about it.Blood: Well, I'd say she certainly had marvelous judgement, Albert, if not... particularly good taste. (laughs uncontrollably)
- Cult Classic: The movie has grown into this in recent years, even becoming more iconic than the novel for some people. It also helps that it went on to inspire Fallout.
- Harsher in Hindsight: In 1977, a couple of years after the film adaptation was released, a mentally unstable man named David Berkowitz (also known as the "Son of Sam") murdered several people, allegedly under the orders of a dog that could speak to him. Sounds awfully familiar, doesn't it?
- Hilarious in Hindsight: The android henchman is named Michael, who is mute, large in size, immensely strong, highly resistant to bullets, moves very slowly, has a chalk-white (due to the makeup he wears) emotionless face, and can brutally kill people with just his bare hands. Three years after the film adaptation was released, another movie would use a character with this same description as its antagonist.
- Squick: The "milking" scene.
- What Do You Mean, It's Not for Kids?: Based on the fact that the title is the archetypal A Boy and His X formation, more than one parent or grandparent has taken a child to see this movie. If there is any scene in this film that's appropriate for minors, it's very short.
YMMV / A Boy and His Dog
