I've had the same experience (+MA via a theatrical rerelease, though I also saw it during its initial theater run!). It has been immensely fulfilling.Introducing Kon's films to my partner has been a joy. We saw Perfect Blue in the cinema and watched Tokyo Godfathers last year and he loved both of them. Really need to watch Millenium Actress again as I've only seen it once and don't remember much of it now.
I've really enjoyed digging into his manga output as well. Opus is great, and there's a book of his super-early one-shot work called Dream Fossil that's very cool. It seems there's more, I'll have to stick those on the list...
Edit: Watched the trailer, yeah this might make me cry
Are there any other creatures or specific films I should be checking out that could scratch that Satishi Kon itch?
Will be watching this one. I'm not a huge fan if anime, though I did have a stint in my teens and early twenties where I watched stuff like Evangelion, Samurai Champloo (never got into Cowboy Bebop), Trigun etc. but that kinda faded quickly. That said, if there's any anime I've legimately loved, since then, outside of Studio Ghibli, it's Satoshi Kon. I've yet to see Perfect Blue, but all the other features I've seen have been near flawless. And I remember Paranoia Agent showing up as a series that I actually enjoyed, after I'd pretty much stopped watching anime. The guy had one hell of a mind for visuals and storytelling. And it rarely, if ever, felt like it was relying on anime clichés.
