I really liked this movie. The relationship felt pretty natural in the context, it had nice foreshadowing, things didn't really feel forced, the fight/action scenes felt nicely coordinated, the acting was amazing, and it was nice to have it explicitly show that not feeling any pain is a bad thing that doesn't make you a "superhero" and that it is a medical condition at the end of the day. There were a couple parts that were a little silly feeling to me, but that's personal just preference that didn't ruin my experience.
