In my Otaku years, Death Note was probably one of the firsts anime/manga I've herd about. But I was like Twelve at the time >3< and I was too fragile when I saw RYUK and I was completely freaked out.

Six years later my sister comes up to me and says "Hey I watched a Death Note Live Action and it was cool" and I was like Hmpf, I remember it. But my curiosity and my hunger for a new anime grew and I sat to watch it.

When I saw RYUK again after all those years I was like whoah, he's scarier than I remember it but then I saw the apple thingy and the following-Light-everywhere-cuz-I-have-nothing-to-do rutine and I was like ... and
Now for me RYUK is OwO, OMG, WTF, LOL, LMFAO!!!!

Moral: Don't judge a Shinigami by his cover
