Film is a medium that is constantly evolving. It responds to changes in technology and to changes in society. One of the largest and most important evolutions that film has made within the last half century is the adoption and use of Computer Generated Imagery. This has allowed films to bring audiences into the story like never before, however it does not come without a price. While CGI has been a very useful tool in film in some cases it has destroyed films and made them look cheap. Either way CGI is an important part of modern day films and cinema.
