2012's Looper is a mind-bending temporal adventure that ends without sufficiently addressing one of its most mysterious elements. Looper is dense with lore, especially for a two-hour movie, but certain aspects of the world created by writer/director Rian Johnson are only touched upon during their presence in the story. While this vagueness around certain aspects of Johnson's worldbuilding helps to create intrigue, other parts of the movie's canon would have been more rewarding if additional details were provided before Looper's ending.
