Lucy is a shit, Transcendence is another one. Why? Because they take a lot of myths about the brain to try to entertain to the public like that we only use the 10% of our brain “power” (if anybody knows what the hell is this). OK, OK, you can say that is fiction and that they can do whatever they want. But the problem in a scientific way is that this “hollywood” behavior help to sustains all this lies in the population mind increasing the ignorance level.
In the other hand, this days the neuroscience results are awesome, is perfectly compatible make nice movies with a high respect for the science background. Examples of this are Paprika, Ghost in the Shell, Inception, etc.
