OK, I know this is considered a classic, and I’m ashamed for not having seen it sooner. I’m even more disappointed because it is also so dated now that it diminished the experience. While it captured the early-mid 90s relatively well, particularly riffing on police procedurals of the time, other aspects now clash. For instance, the long explanations of how the internet works were probably necessary at the time fora portion of the audience, but ring hollow and annoying in 2020. That isn’t the fault of the movie, but certainly had impact.
What sets Perfect Blue apart from much of anime is the story. I think there are better reality-based anime out there, most by this same director, Satoshi Kon, who wrote and directed some of them: Millenium Actress, Tokyo Godfathers, Paprika. But this was his first attempt. And none of what followed quite dives into the darkness of the human psyche quite like this first movie does. Of course, sometime Kon collaborator Sadayuki Murai (Knights of Sidonia) adapted this story, not Kon himself. But it clearly opened a path for movies that followed.
That sets it in context, but is it really a good movie? Yes and no. It’s a challenge to watch at times, particularly for the first third. But as it comes together and it reveals itself, it becomes intriguing and then fascinating. The freedom of animation allowed Kon and Murai to explore the mental disconnection of a person in distress and make it as real for us as it is for them. It isn’t a perfect end result, but it is impressive as it whips through the final third of the story. As part of your anime education, this does have to be seen, but know it is fraying a bit around the edges thanks to time.
