Well, microwaves act by being in phase with the vibrations of molecules. Blood plasma is a mixture of water, salt and blood cells, the water molecules not being bonded to anything and so have the same vibration frequency as distilled water. Same with the vitreus humor of the eyes.

Microwave ovens work because organic matter contains large amounts of water in them. A perfectly dry substance wouldn't heat up in a microwave.

You're making me think too much. The movie was still damn good.
