The whole point of the movie is to point out the absurdity of these types of movies. Quickly, we realize just how ridiculous the whole scheme is, all the way down to the person who "did it" but we still watched the movie. Figuring out the murderer was easy, and this was done on purpose because the movie isn't a "whodunnit" movie. It's essentially making fun of modern society and the people in society. YouTubers who are trying to make it big, even though they are in their thirties and forties. Dumb rich girls who are oblivious and have no clue what sweatshops really are because they don't understand the world. Even a representation of stoner dudes whole are just "out there" doing nothing or having no significant impact in the world. Viewing the movie through that lens, it does a pretty good job. Everything else about the movie is terrible.
