Back when I was in 7th grade, we had to write short stories in one hour. I decided to write a story about a group that wanted to use a magical artefact, then ended up arguing about whether or not to use it. One ended up using it anyway and getting possessed, which was supposed to be the climax. I ended up running short on time and had to cut the possession, making the argument the climax instead of what was initially intended. That feels like what happened with this movie.
