I know someone brought up I Am Legend as a negative example, but look at the opening scenes of a devastated New York City. Except for the CG animals roaming around, which look awful, showing New York City like that would have been impossible without the use of CGI - and it looks pretty damn good to me. That's something that was necessary for the story that couldn't have been done any other way.

Yeah, that was me who used I Am Legend as a negative example, but I also said in the same post,

"In the exact same film, the over grown and abandoned city was also CG, and it looked absolutely breathtaking in my opinion. CG is a wonderful thing, but it can be used poorly and excessively."

To me that movie had a lot going for it, but they really killed it with lazy film making.
