What's so good about it?

I have heard a few people ask this year....and i for one...have never understood, or looked up, or even asked....why GOOD FRIDAY....for heaven's sake, Jesus died on Good Friday the Friday before Easter. Well, as best I can tell, no one really knows the origin of the name Good Friday. There is a bunch of conjecture, but most believe that the name "Good Friday" was adopted or came into origin in the Catholic Church around the 5th or 6th Century.
There are thought to be two possible origins for the name. One was that the day was originally called God's Friday, yet the God was replaced with good, because God's name was viewed as too holy for the commoners to speak. The second, is German in origin and "Gute Friday" literally means "holy" Friday, which makes the most sense to me.
An idea that I saw, in of all places, a website denouncing Christianity I also liked......it basically said that the day was 'good' because it put into motion the events that would 'keep people out of hell', and that is good.
