The characters spoke too quickly to each other, and didn't seem to be actually talking or interacting with each other. It was more like a performance, just to be impressive.
They also did all the wrong things, which seems to be a trope for these kinds of horror/thriller types of films, but it just ends up annoying me. I would've got out of that Green Room a hell of a lot faster than they did.
One thing I did like about the film was the way it slowly drip fed information to us, so in a sense it was well written, and I did find myself wanting to know what was going on. I give it a 6/10.
My viewing partner hated it, thought it was too violent, and gave it a zero.
