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.
Asshole Victim: The filmmakers admitted (gleefully, in fact) that they wanted the teenaged victims to be as annoying as possible in order to make Jacob Goodnight look cool (as if that was even necessary for gore-loving horror fans). Problem is, the kids just aren't quite annoying enough to justify their murders. The fact that they're in that hotel against their will and are pretty much helpless also tends to lend much sympathy to them.
Base Breaker: Danielle Harris as Amy in Part 2. Some fans love Amy's Nice Girl qualities and strength (with Danielle's status as the current reigning Scream Queen helping out), while others feel that Danielle's overacting ruins an already generic and uninteresting character.
The Scrappy: Micheal is one for most people, considering he's a sexist a-hole who a had previously been Kira's boyfriend and abused her. The fact that he lives in favor of Ty, Melissa or Ritchie doesn't make it any better.
