Basically every modern action movie needs its entire CGI budget slashed and used for wires and fireworks and garish costumes. Even Avatar would be good if it had hundreds of men in shiny foil robot suits launching acrobats in blue jumpsuits hundreds of wire-assisted feet into the air with enormous sparkler explosions.
Counterpoint: I would kill to see this scene with full CGI support and IMAX 3d. The thing that makes this completely insane and wonderful isn't the admittedly lovely hand-drawn laser beams, but the literally insane pacing.
