One thing I've noticed about CGI complaints....no real frame of reference....
What I've noticed about people negatively critiquing today's CGI and the like is what seems to be a lack of a frame of reference.
Those of us who grew up with the special effects of old often have a better frame of reference when it comes to the progression of special effects of years ago to that of today. And I think knowing what we had to sit back through back then allows for a greater appreciation of CGI visuals today.
