ITT old people moan about CGI....and how it was better in the olden days when models were used...
You should listen to them; old people have more refined taste.
I love good CGI. Star Trek '09 had fantastic effects. This YouTube video, while excellent for a fan creation, is not up to that standard, or the standard of physical models shot on film. And I should know, I make bad CGI myself.
I'm not old, though. Yet.
