Anyhow, more related to Episode VII. Did anyone else see Oz; The Great And Powerful? It used a couple CGI heavy sequences, but most of the film was practical and mainly used greenscreen as set extensions and matte backgrounds. If they can't match the lack of CGI in the originals, they could maybe atleast do something like Oz.
