To be objective:
>The art is pretty
>The characters don't have a ton of personality but also aren't grating, and are suitable vehicles for this story.
>The writing is excellent, if you can ignore how the characters occasionally muse about philosophers, physics, and the time-space continuum in dense and absolutely unrealistic detail. Because of that there's a few pages I skimmed or mostly skipped to get around the smarter-than-thou textbook dialogue, but in the end it doesn't detract much from the main narrative.
This story, at times, wants to be very intellectual (too intellectual, really). But at it's core it wants to move you, and it wants to paint an emotional story about teens trying to find meaning in both the world and their relationships.
Teens are probably the best audience for this, but I think most people can appreciate this story. If you're a medically fragile person like me, it might wreck you emotionally. Sometimes that's exactly the kind of story we need.
