In episode 2 there was a technical mistake concerning the aluminum chair involved in the lady's electrocution. When the Detective placed the TWO CLAMPS from the generator, the electrical circuit (path) would have BYPASSED the lady's body BECAUSE the current would have flowed STRAIGHT across the top of the aluminum ( a good conductor) chair.
all that would have happened is a high current would have been produced due to low resistance and the Generator circuit breaker or fuse would have popped and stopped ANY current flow.
If she had been sitting in a plastic or wooden chair ZERO current could flow into her body because they are insulators.
For the movie to be technically correct ONE of the jumper cables would have to be placed at her feet in that blue anti-freeze stuff. And we would still have to assume that that stuff was a conductor. Also, to kill an adult you likely would have to have a generator that supplied greater than the usual 120 volts that the movie showed was powering the close-by string of lights.
