* Whilst the heartwarming is minimal in this film, the scene where Mark, upon reaching [[spoiler: his mother's deathbed]], ends up [[spoiler: inventing religion, changing the world and its outlook on death simply so she can spend the last few moments of her life happy]] definitely qualifies for this.
* His refusal to abuse his talents, such as getting people to sleep with him or lying about his genetics to his love interests, even if it costs him the relationship, are also quite nice.
