4. Make Sure We Care Before You Kill
The new film populated itself with the usual characters that you'd find in a horror flick, and it did a good job of subverting expectations. They weren't a bunch of horny teens trying to have a fun weekend, they were concerned friends trying to make sure someone they loved and cared about got clean. If you were looking for more in our characters, I'm afraid you'll have to go to another movie, because that's about it. Concerned Friends 1-3 were brought in, taken over, and brought out. Rinse, repeat, flash The Chin across the screen and promise a more interesting sequel. And that more interesting sequel needs to have characters we care about before they're killed off. If you kill a character without developing an emotional attachment with the audience, then you're basically just killing for the sake of killing. Horror movies do it all the time, but they don't waste an entire film on it. Evil Dead did, and Evil Dead 2 shouldn't be allowed to make the same mistake.
