I agree. I think Lost shouldn't just have the characters be black or white (completely intentional pun

). I mean they shouldn't be good or evil rather shades of grey. I don't think the Man in Black is inherently evil just views humans differently to how Jacob sees them. And how can Jacob be some form of good guy, because he was the one who brought Oceanic 815 to the island in the first place (a pretty sadistic action). What sort of good guy brings people to an island then essentially tortures them, and kills most people on the plane in the process.
And that video is pretty cool. If you watch it you can see how the new timeline (where they don't crash) is much brighter (a reference to the colour white, perhaps) and there are some changes which are documented in the comments at the linked website.
