... well, sci-fi movies, at any rate. I remember when C.G.I. was making it's first appearances (I think around the time of Terminator 2 and Jurassic Park) I was rather excited, thinking that there would be a lot more science fiction movies produced because it would be cheaper/easier to do so, and that this would be great for fans like me. Well, I suppose I wasn't completely wrong, but when I look at all the dreck out there these days, I certainly wasn't right.
Even today, 20+ years after the first "photorealistic" C.G.I. creatures of Jurassic Park and Babylon 5's space station, C.G.I. still, largely, looks totally fake and stupid. My children have been watching Empire Strikes Back over and over and over lately, and the ships in that (1980) film, or how about the Aries 1B Earth-Moon Shuttle from 2001: A Space Odyssey (1968!) look far more convincing than, say, the ship in Avatar (2009) that transports Sam Worthington to Pandora.
This also applies to scenery and human battlescenes -- consider the future war scene from Terminator 2 which unlike the T1000 was all models, Animatronics, and "practical effects" (they actually flip the truck, for example). By 2003 with Termintor 3 we got a whole platoon of risible cartoons walking stiffly down a hill. Or even the battlescenes in the Lord of the Rings films, which was probably some of the best C.G.I. I've seen -- it still looks fake because it is.
(Youtube won't allow an embet of the T2 battlescene, but here it is: http://youtu.be/N9YU0hQEZ5M?hd=1)
The battlescene in T3 starts at about 2:55 of the clip below:
And don't even get me started on puppets vs. C.G.I....
And the list goes on -- guys in rubber suits (Alien in '79/Aliens in '86) make for way scarier xenomorphs than the C.G.I. nonsense in Alien Versus Predator.
The thing is, if I had the wherewithal to make a film, all I'd have to do is wander down to the local gaming store and hire all my fellow Warhammer geeks to build and paint-up a whole mess of scenery and vehicles. With less than the cost of one scene of C.G.I., they could whip-up a while galaxy worth of stuff. Now, maybe there are some union issues or something, but C.G.I. just strikes me as the lazy film-maker's way out and it has led to poorer filmmaking. In the old days they had to actually use their heads and get creative, not they just use computers.
