I finally watching Perfect Blue after being recommended it for years whenever I talked about fandom / obsession / the internet, which is a lot — it did not disappoint! Truly horrific and brilliant and unique.
I didn’t read too much about it beforehand, and I recommend going in the same way, and coming out just as confused. I love finishing a film and immediately searching for articles and blogs and reviews.
(The exception to this would be if you need to check trigger warnings… I would do that(!) for sure.)
