Since there already is a different thread beside this one, I'll try to explain why this thread is different from the other one.

In the topic ''anime must see'', you tell other people what kind of animes you think they should watch, but here I'm talking about the anime that really impressed you, the anime you still remember and the anime you think totally rocks your head off!

So what anime is it, and please explain why you think this is the best anime in the world.
