Okay this movie has got some concept. Due to some solar flare Human brains got rewired so no one can sleep. I was hoping the cure was an another electric shock, like from a defibrillator, which can restart the brain, get the sleep nerves going. Yeah something like that. Something logical. That's when the plot derial. Turns out you ought to die to get your sleep back! Bummer! I am giving it 3 star because of the ending
