i don't know how you could have a superman without the fantastic element. to me, the climactic action made me really wish they did that clarity and realism for a real dbz film. as for the akira reference, i think you're stretching it there. in akira, the satellite served a particular purpose, that of a massive weapon.
as for the contrived element you refer to, i agree, but this is normal fare in any drama. it doesn't matter the context but the characters tend to stay involved in the story one way or another. in reality, the cast of characters dynamically change, but this doesn't work within the finite timeframe of a film. it could have been handled a bit better, as i noted earlier. just a little sloppy, not really a critical dealbreaker imo.
