* AdaptationDisplacement: The movie is far more well-known than the novel at this point; people who seek out the book may be shocked that it's a character drama about the guilt the characters feel over the hit-and-run ([[spoiler:a little boy in the novel]]) and having to cope years later while dealing with the title-based note.
* EnsembleDarkhorse: Helen, so very, very much. There's no shortage to the fans that [[spoiler: wish she had been the final girl with Julie dying.]]
** Karla has quite the fanbase as well.
** Nancy is proving pretty popular as well.
* FanonDiscontinuity: ''I'll Always Know What You Did Last Summer'' Many fans ignore it for having no connection to the previous two movies, it's been also criticized for it's writing, acting and characters, and there's TheReveal that [[spoiler: Ben Willis is now a ghost or zombie]].
* HellIsThatNoise: That ungodly shriek [[spoiler:Ben makes in the third movie.]]
* HilariousInHindsight: The first movie had [[Series/GhostWhisperer a girl who talked to ghost]] and [[Series/BuffyTheVampireSlayer a girl who kills them]].
* IdiotPlot: A major complaint of the second movie especially.
* MemeticMutation: SOON
** '''[[NarmCharm What Are You Waiting For, Huh?! WHAT ARE YOU WAITING FOR?!?!!!!!!]]'''
** The title.
* MoralEventHorizon: The teens in the first movie, as they decide to throw the body into the ocean to avoid going to jail for DUI and vehicular manslaughter. The JerkJock ''really'' crosses the line because [[spoiler:he dives in after the body, to make sure it stays sunk. While there, he's the only one who sees the EyeAwaken of the victim, ''meaning he KNOWS that the victim is still alive''! He just swims away, then pressures the others to keep the secret when they start to relent.]]
** Of course, the victim had [[spoiler: just come back from committing a murder himself, so it's not like he's entirely innocent.]]
** Barry in the book [[spoiler: He's the one most responsible, as he was driving, but he's the least affected--his sole concern is covering it up. Then after he's shot, despite knowing full well that the perpetrator is the person who has been stalking the group, thanks to the threatening phone call he received just before it happened, flat-out lies about it, first by claiming that the call was from Helen, thus allowing his parents to blame her for his injuries, then lies to Ray and claims it was a random mugging gone wrong, thus allowing everyone's life to be in danger, proving that he really doesn't care about anyone but himself. It's hard not to feel sorry for a guy who might be paralyzed for the rest of his life, but Barry pushes it pretty close.]]
** Some might say [[spoiler: Collie crosses this when he shoots Barry. There's no doubt that he has every right to be angry at the group, but turning them in would be a lot more tolerable than taking the law into his own hands and deciding to KILL THEM all, especially considering that three-fourths of them were genuinely shaken up and sorry about what had happened.]]
* RetroactiveRecognition: Two CBS examples, Max is [[Series/TheBigBangTheory Leonard]], The Fisherman is [[{{NCIS}} Mike Franks]].
* TheScrappy: Ray.
* SpecialEffectsFailure: When Tyrell gets hooked in the neck, the blood coming from his neck is obviously CG. It disappears into thin air, and none of it stains his T-shirt or skin.
* TheyWastedAPerfectlyGoodPlot: After the first film builds a nice amount of tension over who the killer is, he turns out to be someone we've never heard of.
* WhatAnIdiot: Barry knows someone wants to kill him. Said person even tried to run him over. So what does he do? Why, he ends up going up to a dark, secluded balcony all by himself.
** Helen is no better. After a relentless pursuit, she runs through an alley and comes upon a parade full of people - only to stop and check if the killer has caught up to her yet. Naturally, she would've gotten away if she had just kept running. Of course, she could not have seen the OffScreenTeleportation coming...
** And in the second film, Julie is trapped in a tanning bed that's been turned up to the highest setting. When her friends discover her, they immediately set about trying to bash the bed open. None of them thinks of unplugging it first so Julie doesn't burn to death.
