What year is this? xD
Incidentally, I'm currently replaying Dark Souls 2, so it was kinda surprising to see this thread come up. And the game's lightning took a big hit indeed. Supposedly the "torch lightning your path mechanic" was going to be far more prevalent than it ended up being on the final version (which you'll barely ever use the torch aside from the start and maybe the foggy forest area).
Also that "Dragon breaks the bridge" thing...yeah. I mean it's still in the final game but good luck triggering it (why would you, anyway). I always thought you have to kill every dragon before proceeding or they'll break the bridge, but nope.
I don't really have a problem with the final build at all, except for that washed-out colours. Still, it looks good, although I've always had the odd belief that Dark Souls 1 looked better in certain areas.
