Perfect Blue is a movie that will keep you guessing the whole time, always wondering what the significance of events will turn out to be in the end, what sort of people the characters are (good or bad?) and what the fate of the main character will be.
Perfect Blue has elements of murder mystery, psychological thriller, drama, action, and perhaps even horror. Be warned: there are some fairly graphic scenes of violence, and a challenging-to-watch but nonexplicit rape scene which is part of a movie set script and which we see filmed for a movie, as the main character is trying hard to become a successful actress, taking on roles she is uncomfortable with to establish a successful career. This is only appropriate for adult audiences, and I watched this first without realizing this fact, so some of what I saw surface in the film surprised me a little bit.
If you like suspenseful and complicated plots and mind games, surprises, action, and horrific suspense, then you just might enjoy this. If this description interests you, then definitely go for it.
