Has anyone else seen this? What I didn't get was, if they were all in pods, like in the Matrix, and actually in a dream like state, why were they (in their dream like state) trapped underground and forced to eat healthy food etc? Why not have have them thinking they were in the real world? Or would that be too much like the Matrix?
They weren't in pods - they were living a "false" life underground. The healthy living was so that their "parts" would be in good nick for when their "real life" counterparts needed to harvest them.
The pods were to accelerate the growth from egg to adult, after which they lived "normally".
