These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Pilot Candidate
Angst? What Angst?: Erts seems to care little about his brother's death. But he's kind of emotionless to begin with.
Crowning Music of Awesome: If there is one thing viewers will consider good in this series, it was Tomoyuki Asakawa's fantastic score.
Ho Yay: Expect no less from the author of D.N.Angel. To begin with, the scene where Zero and Hiead meet. That classic situation where one party (Zero) is going too fast and ends up falling on top of the other (Hiead) and accidentaly straddles their hips. And in the last episode, Hiead saves Zero from Victim for reasons he doesn't even try to explain.
Don't forget Ernest. He was in love with his best friend Gareas, who was completely oblivious to his feelings. But that didn't stop Ernest from loving him and pulling a Heroic Sacrifice in order to save Gareas.
