Ocean's Eleven/Fridge

Fridge Horror

 * In the remake of Oceans Eleven, the thieves set off an electromagnetic device that shuts down all electrical systems in Las Vegas just so they can break into a vault. Initially, it seems like a Crowning Moment of Awesome... until you stop to think about all the pacemakers that must have gone berserk when the pulse went off, or all the cars that went out of control, or all the planes and helicopters that fell out of the sky, or all the doctors who, in the middle of performing a delicate surgery, suddenly found themselves plunged into complete darkness. It becomes a lot harder to root for Danny's crew once you realize that little stunt probably killed dozens, if not hundreds, of people. Danny specifically states he wants an EMP that could knock out "all of Las Vegas". That's exactly what they get. They also take into account that the casino has backup generators. Admittedly, it only lasts around a minute. Not sure how scientifically accurate that is, but for the world of the film, they somehow manage to knock out ALL the power in Las Vegas for around sixty seconds.
 * Actually, in real life, pacemakers are specifically constructed with material that shields Electromagnetic Pulses.
 * Also most hospitals are equipped with generators in case of a power failure. Otherwise people would die every time there is a thunderstorm.
 * The machine in question would also fuck with backup generators, or at least the real life version would. It takes out any and all electrical systems, including backup power sources.
