Mamoru Oshii crafted a fucking masterpiece with his "Patlabor 2: The Movie" (1993). A deep film, loaded with remarkable, detailed imagery created during the peak of cel animation (the scene where the Hellhound attack chopper is reflected in the mirrored windows of a skyscraper is just beautiful). Some terrific trademark Oshii montages set to Kenji Kawai's score create a singular atmosphere (I just love the montage in which tanks are deployed in a Tokyo snow scape).
I miss the era of high production value movies like P2: Ghost in the Shell, Akira, Honneamise, Jin Roh, Galaxy Express 999 (Leiji Matsumoto era - Arcadia of My Youth also amazing),...the list goes on. We're not likely to see the likes of such theatrical anime again.
