Eliezer, did Morpheus' allusion to human body heat spoil the movie for you? If so, you're doing it wrong.

Where does your pedantry end and your suspension of disbelief take over? After or before the antigravity ships? How about the genocidal robots? What's your rationale for watching the movie in the first place?

Tim, the guy you quote is making the same mistake. If you need to postulate some nonsense about Morpheus' superstition for the plot of a movie like The Matrix to 'sit right' with you, then I say again, doing it wrong!
