Get the shading right, the lighting right, and there are things you can do to make the CGI look more real. People end up going crazy and give themselves a little too much freedom in how they use CGI, and if you overuse it, it draws attention to itself.
Sentiment: NEGATIVE
Even today, a lot of the CGI you see in movies is so clean and crisp that it just looks fake. It's weird: the more advanced they get, the faker it looks.
