The Matrix cliche in general killed me (no pun intended). EG. if you unplug a person from the network, they'll die because "the brain can't live without the mind" or somesuch. This is like assuming that unplugging a network cable will cause your computer to self-destruct.
I can accept pulling the plug killing people... maybe it's the shock or something to their brain to have a sudden disconnect that actually kills them. It's the dying in the Matrix kills you in real life that I don't like, with the whole "the mind makes it so". So the mind is causing organ damage and internal bleeding just because it thinks that it's injured? Glad my mind doesn't do that!
