Does a kidney have memory cells like the brain? The brain of the donor was declared dead while the kidney took over the memories from the dead brain and kept evolved during the transplant surgery. When it was planted in the receiver, the kidney would be immediately carried the torch of revenge, automatically manipulated the kidney receiver to do something for the dead donor and, if the guy who died violently got a violent history, would he signed up a donation consent for his body organs during his annual renewal of his driver license? I don't think so since he's not a charitable mankind.
What bothered me most is since when a kidney would carry all the memories, bad or good, from a person? If a kidney is like a part of a computer, or even a memory module, do you think when the computer suddenly dies or crashes, or even just shut down abruptly, the memory module or any part of the computer would still able to carry what the computer did before the crash? So, just tell me, do you think one or both of your kidney would carry all the secrets after your sudden demise and instruct the organ receiver to carry out a revenge mission? The kidney would give you nightmares if you refuse to do so. Where's the logic? If the premises won't hold and you still decide to watch this absurd movie, may God(even this guy actually doesn't exist) help you, man.
