I enjoyed the animation style of L., but the Light Yagami character pissed me off straight from the word go. I couldn't empathise with him, I couldn't sympathise with him, I found his logic and morals faulty from their very foundation. I so didn't care what he did or what happened to him.
L. was much more interesting and charismatic, and I was pissed with what the story did to him.
I don't think that reverance or respect for the dead needs the dead to be hidden from sight completely. It is the attitude that you bring, as a witness to a dead body, that matters, not the display and witnessing of a dead body, per se.
