ending of handmaid's tale

well the ending left us with a lot of unanswered questions. Offred has slowly gained more and more power throughout the story, but the story leaves us with the eyes coming to get her and doesn't tell us what they do to her, if anything. The handmaids beat a few of the eyes. The society seems to become unhinged and likely on it's way to destruction. The handmaids eventually gained enough courage to rebel and are probably the cause for the chaos. It was an interesting story but the ending leaves a lot of questions unanswered.
