It’s like someone watched a good movie, got drunk and told an alien the general plot, and then the alien wrote a script that he gave to a high school theater group to perform. With Melissa McCarthy.
That's really damn incredible. I've seen horror movies with over ten times that budget that didn't look this good. The plot may be lacking, but the technical prowess and what they made from what they had is so good I can't begrudge them. All I hope is that they are able to expand on that facet in the sequel.
