Chosen answer:Due to the relatively shallow depth that the microwave heat reaches to in a short time, a large chunk of raw meat (i.e. a human) would take a very long time to 'cook' to the core, so the reality of 'bursting' like that is very unlikely; death is more likely to come from the extensive level of damage done to the skin and layers beneath, and the progressive boiling of bodily fluids. It would certainly take longer than a few seconds as portrayed in the film.
