Genuinely don't understand the positive reviews on this. It was a movie that really didn't know what tone it was trying to set, acted out by the most cardboard actors they could find, with a script written with no concept of actual human interaction.
It was kind of fun watching for obvious continuity errors and trying to guess character motivation, but the script, vfx, acting, etc. Fell well short of delivering a cohesive plot. I can understand the low budget of the film and excuse the poor visual effects on that note, but there are so many movies on similar budgets that stretch the budget so much further with better script writing and acting.
I'm mostly just confused because it's not funny enough to qualify as a "horror-comedy," nor is it serious enough to qualify as a true "slasher."
I'd generally recommend avoiding this movie unless you're planning on laughing at something silly.
