Comic book movies are an exception.
Superman is supposed to fly at 99% the speed of light. You don't get that same sensation of 'Wow!' if you just see a guy tied to a string and moving around. With CGI, you can do many things that, while in a book or comic are easily accomplished, are impossible to do without. The bullet breaking against Superman's eye in Superman Returns, for example. Or the dinosaurs in Jurassic Park, or the Terminators. While actors in costumes is all good and fun, the movements are slow and cumbersome. Certainly a testament to their time, but these days can be done much better. With CGI, if the art is done well, you can make all kinds of spectacular scenes that further enhance the movie experience.
That's not to say I, as a product of the current generation, don't love some old timey classics. I'll still watch the old King Kong, The Lost World, or the original Godzilla and enjoy myself thoroughly.
War is an extension of economics and diplomacy through other means.
Economics and diplomacy are methods of securing resources used by humans.
Securing resources is the one necessary behavior for all living things.
War = Life
