> The story made little sense and appeared to have little, if any, depth.
I felt similarly the first time I watched it, but I walked out feeling confused rather than feeling like the film lacks depth. IMO a large portion of the film is spent exploring the notion of power than one can't control. In fact, we can split the different characters of the film into those who are corrupted by this path (the scientist who clearly wants to see Akira's power blossom, the military lead who wants it controlled for public safety/the military, Tetsuo who is always trying to take on more responsibility and leadership then he can. Only character's like Kaneda, who don't submit themselves to their own desires for power, seem to faire well in the world around them .. but that's just my two cents.
> The graphics looked dated and not very inspiring.
I can't disagree with this more. This film came out in 1988, and nothing else even came close in terms of its visual effects for an animated film. I'm sure at the time people couldn't believe what they were watching, it must have seemed really alien.
I'm honestly surprised that you think it looks dated. Even today, animes I've seen (although granted that isn't many) don't achieve the same level of beauty in their animation of light.
