Stupidity: When Charley goes to Evil's house, he asks him how to protect himself from vampires. Since Charley is such a huge fan of Fright Night and watches it all the time, he should already know everything to protect himself from Jerry.
Stupidity: After Jack is found not guilty, you would think the first thing he would do is to get rid of the typewriter he used to send the notes to Teddy to manipulate her into winning the case for him, especially when she is sleeping with him at his home. Not to even mention the fact he hid the typewriter in an unsecure manner in a closet behind a stack of towels, a place where it would very easily be found. This foolish mistake exposed the truth to Teddy and cost him his "freedom."
Suggested correction: Being a fan of horror films in general and watching Fright Night on TV doesn't necessarily give someone expert knowledge of how to fight vampires. In fact, not every vampire movie is consistent with rules (including this one) and it is far from stupid to consult a friend who knows more than you about the subject. Think about it like this: If you watched every comic book movie that was made and every TV show based on comic books, then found out Galactus was real and you had to fight him, you wouldn't ask your friend who was a comic nerd for advice?
