The children don't get frozen, they get incinerated So I guess my lack of knowledge about what happens to the kids in the long term wasn't really my fault. This also explains why CAB was killing all the sisters on sight which confused me for a while. I thought that just maybe a few CAB people were bad but I realized that what they were doing was standard and accepted which was a shock. I read reviews and some people said that this was their favorite movie ever, I wouldn't go that far but it was definitely a worthwhile watch.
