I have to disagree. Renton and Holland especially are stubborn, spoilt characters that doesnt deal with their issues and let's it linger all through the show just to have their moment of redemption/forgiveness later. I agree this is real and human, it's just boring as fuck and about as deep as a puddle. It's clear and obvious emotional reactions. a character like Yuuko (xxholic), Natsume, Rock + Revy have far more emotional complexity.
