Guys… if you think that CGI was good, then we really don’t have anything to talk about. No offense at all intended.
Just as a quick, rough example, compare just the Deadpool model to how Rocket and Groot turned out in GotG. That’s good CGI.
Like I said, the Deadpool teaser isn’t even a teaser, it’s a proof of concept for movie/studio execs.
If you’re talking something which is 90% dialogue, you’re correct. In this instance, you’re not. An equivalent live action concept containing the same action beats, would have a ridiculous budget.
