It's classified as a teen slasher film, though unfortunately, it’s not among the better examples of the genre. The filmmakers seemed intent on highlighting a particular plot development, which proved to be problematic because the tension doesn't develop in a manner that allows viewers to connect with that reveal. It simply occurs, and there isn’t much reason to suspect what’s coming. This results in a film that feels lifeless and easy to anticipate. A relatively simple adjustment could have improved things, but instead, they opted for an obvious approach, leading to the final product. It's disappointing.
