“Spencer” is not quite narrative in the traditional sense. Sequences without consequence to the plot make up the majority of its end, opting instead to swath the Princess in a fantastic, symbolic air. While this is not necessarily something to dislike, it does not fit as neatly into the genre as some viewers may have expected. This film is likely to be polarizing amongst both general audiences and fans of Diana, who go in anticipating a biopic but come out with an entirely different experience.
