Continuity mistake: Marty is in a school shower stall facing outwards. It is a close shot. He is dry and completely naked. He covers his genitals with his right hand. A large swath of the top of his dark pubic hair is plainly visible. In the next shot, as he exits the shower and moves to his right, he is still completely naked, however, he appears to be covered in thick soap suds from above his belly button all the way down to the lower part of his thighs to the point that his pubic hair is not even distinctly visible. (00:05:50)
Continuity mistake: In the introductory scene, when Carol tells Marty she is wet all over, we see that Marty is wearing black underwear. In the very next shot the underwear has disappeared.
Visible crew/equipment: When Skip has just finished snorting cocaine and is talking to Stella, the boom microphone is visible on the top left of the screen.
Continuity mistake: In the scene when Carol is running from Marty, she hides in the gym. Marty runs into the gym. Carol runs out and goes down two flights of stairs. She then goes into a room by the stairs and goes to the window...the window that overlooks the gym. Somehow having gone down two flights of stairs Carol has ended up above the gym.
Audio problem: Although the protagonists are all American, the actors are all English. This is why several characters mysteriously switch accents part of the way through the film - Marty speaks with a solid English accent after his first few lines.
Plot hole: The school is supposed to be rundown and closed after ten years yet Marty somehow manages to get in, rig up all his traps (including the acid through the bath pipes), and setup the reunion supplies without the caretaker ever catching on to anything that's going on. It also begs the question if the caretaker was there the whole time until he was killed how did he not notice the other students waiting outside for several hours or their cars to ask what they were doing while outside?
Plot hole: When the bullies take revenge on Marty, they doctor the chemicals he is preparing so that they explode. The bullies were punished some time in the afternoon, judging by the sun in the very first shot. Their detention is at 4:30 in the afternoon. Somehow, they manage to acquire the necessary chemicals for the explosion within a couple of hours, even though they are stuck at school. In addition to this, they have no way of knowing what chemicals Marty is preparing, so even if they were able to get chemicals, they would not know which ones to get to destroy his experiment.
Revealing mistake: The scene in the locker room when the bullies are dunking Marty in the toilet. Marty's "body" is a fake prop used - on the naked body mysteriously there is no penis or testicles. In addition to this, despite being turned completely upside down, Marty does not struggle in the slightest as he would in real life - he does not struggle at all exactly because it is a prop body being used.
Answer: Some people are not the brightest button in the box. If wanting something enough they will overlook the obvious.
