"The movies mistakes are: (1) to limit Powder's activities to the conventions of genre pictures, instead of exploring his effect in a more realistic world; (2) to prevent his enemies from learning from him; (3) to upstage his emotional insights with his electricity tricks; (4) to fail to explain his reality, so that there are no rules to create discipline in the plot, and (5) to expect us to be satisfied with an ending that settles less the more you think about it. The sad thing is, when movies like this fail, Hollywood executives think this proves there are no audiences for original, unusual pictures. Because they think they made one."
