You see through the initial concerns of the team and the achievement of the end result, post production companies are perhaps still well in demand and striving to take VFX further and further.
In conclusion, I am still somewhat concerned when modern films place too much emphasis on VFX. At the end of the day however, computer animation is just another tool for a film maker to communicate their vision. There are just some things that cannot be achieved with puppets and sets alone. Although computer generated effects are not always realistic, neither are traditional stop motion methods for example. It is this new attitude that has allowed me to come to terms with George Lucas's 'Star Wars' re-releases. Some of the new VFX heavy scenes were possibly intended in the originals. The smooth camera flight through Mos Eisley (the pirate city located in Tatooine), would not have been achievable in the late 70s. Now modern technology has enabled lucas to go back and share even more accurately his vision. Most importantly, beneath the new computer effects there still lies a gripping story, showing both narrative and VFX can work hand in hand.
