These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Maximum Overdrive
Awesome Music: Any song for AC/DC fans, but "Who Made Who" stands out as the one of the three sole original songs in the soundtrack.
Cult Classic: Thanks to its silly premise and a rocking soundtrack by AC/DC, this movie has its fans. (Not to mention a lack of other "machines take over" movies to pick from.)
The Scrappy: Connie. Nobody can stand her constant screaming and whining.
So Bad, It's Good: Stephen King himself making a movie based on his works? What could go wrong? Cocaine, mostly.
The wheels on the Lawnmower that attacks are not flat on the ground, giving away the illusion that its not remotely controlled (it was also responsible for giving the cameraman an injury to his eye).
The soda machine has visible tubes that hurl the pop cans out.
The steamroller loses its steering wheel after it crashes through the scoreboard.
The stove top that the waitresses' elbow gets burned isn't turned on.
The ice cream truck that landed on its roof (a malfunctioning stunt that almost killed another cameraman).
The Mack truck that chases the newlyweds has different pedals between two scenes.
The matte painting of Earth at the beginning is reversed.
The stunt driver of the beer truck can be seen when it rams Curt and Connie's car. Later, the Ice Cream Truck's driver is visible just before its blown up.
One of the soda machine's victims doesn't die right away.
The Mack Truck explodesbefore going over the cliff.
When Hendershot uses the rocket launcher, no rockets are shown being fired.
In a behind-the-scenes example around the trucks. The radio-controlled versions (which were full-size) would usually break down during filming the Dixie Boy destruction, delaying filming. And when a truck was fixed, another one would break shortly after.
This was the reason for the infamous deleted shot that allegedly made George A. Romero throw up. The dummy was built to release its blood packs as the steamroller passed over it and the blood was supposed to simply smear across the roller, but instead the blood packs all pooled up at the dummy's head and burst all at once, resulting in a shot that was deemed too overly gory for the finished film.
