Not only does the update make the game look better, but think of the other way's it can be used. It can be great for film making and even greater for build's to have the effect they are designed for. I personally love the update. The real reason people didn't want it was because of the nostalgia factor of The Bedroom, Kitchen, etc. As Kompressor said, it's time to move on.
But don't get me wrong, I will miss the maps too.
