Everyone’s complaining about the dumbness of the use-100%-of-your-brain premise for Lucy. (Which I expect is a bad movie.) I have an idea for a superhero that I think fixes this problem. Coaches are always yelling at players that they need to ‘give 110 percent!’ out on the field. So: what if someone actually figured out a way for you to do that? (Makes you think, eh!) You could have these amazing scenes where, after the super-sciencey treatment, the hero is being tested. Running on the treadmill, solving math problems, stacking raisins. In each case the guys in labcoats, gathered around the readouts are smiling, amazed. ‘Sir, we’ve done it! He’s using 110% of capacity!’
The point being: this guy (or gal!) is going to be able to beat Lucy, whoever she is. End of story. Mischief managed.
