And I think some of you have some really screwy ideas about CGI. It's a tool to achieve a certain illusion, same as any other from the filmmaking trade. If it's a choice between something looking exactly the way the director wants via CGI or else a hackjob, bastardized shadow of how he originally envisioned, I'll take CGI everytime.
Esp since all effects (rubber masks, miniatures, CGI, whatever) all look fake to me anyway so why split hairs over which looks faker?
