I think I made it half an hour into the movie before the stream of incoherent hashtags had me rooting for the protagonist to get killed. There were a few brief interesting moments when Christopher Lloyd makes his entrance but the succession of characters that wander into the lack of a story just remind me of how unprepared our hero is for her adventure. As a "scientist" she should be worried about the real physical harm that can come to somebody wandering into "a rat infested pit covered with graffiti", to borrow a line from the movie.
The story had some potential but it went nowhere for so long that no payoff could ever be worth the wait.
