If you take away the CGI, there is nothing to say about this ...movie(?)!
Beyond that, what's next? Bruce Lee being impersonated by Will Smith? Napoleon by Denzel Washington?
Creating diversity in movies is a common sense but not by replacing colour of skin only. The sky is still blue. When is red, either something goes wrong either there is a nice sunset ... Then we have The Meritocracy! If you are a good actor is not because your color of skin but because you are talented. I regret that I paid the ticket to see this ...movie(?)!
