I haven't seen or read it, but based on your review, it sounds like a great book. I have a small critique on your protagonist view I just really want to share.

We're all used to hero snowflakes staring the plots. Above average people who, as you stated it yourself, evolve. But people usually aren't like that.

The way this book depicts a common person in it's world who decides to pursue a goal is very intriguing to me, so much that I now plan pick it up just to see how it develops.

Thank you for the review!
