I saw Akira so many times that my first encounter of "its really only in the movies" was when I tried to jump off a moving motorcycle trying to evade the police as kids when I wasn't wearing a helmet. It hurt for half a year. The police saw it happen, drove by, and only laughed at us, we looked like learned our lesson, limping by.
It took me a lot of watches to understand what was going on, being a Dutch kid pre internet. The vhs deteriorated, and finally my VHS player ate it.
Later on, I met some guys doing shady stuff with DVD's, wich were hot at the time, and they managed to get me an original one. In Korean. But I knew everything they were saying. "Red Bennies*, three of them." "Hey, this isn't a dancehall sport!", "Lighten up pops, before your artery(?) is blowing". It has been many years since I've seen it.
Eventually, I heard about a remastered edition, wich I ordered, and it kind of sucked. But the cd with the moviemusic, that was a masterpiece. Really. The music made the film.
And it's the only manga I ever really liked. I'm not manga guy, but I honestly think being a manga doesn't do it any good, as people will expect things they usually see nowadays.
So. Yeah. I think it's a great movie, and the music did that.
