Every pixel of those things was smeared over with a vaseline like layer of digitally colour corrected to f*ck awfulness that made everything look fake. Which is probably why some overestimate the amount of CGI in the PT... but there is still a ludicrous amount of it with no good reason.

I can only speak to the one prequel I've seen, but those are my thoughts on the CGI as well. I had to go to screencaps to refresh my memory. I wonder if there are any more than just a handful of scenes that haven't been overly and unnecessarily processed in some way or another.

I remember at the time thinking the film looked like a video game, but looking at screencaps now, clearly I'd forgotten just how much it looked like a cartoon. The outdoor scenes are particularly jolting. The scenes where I know there is a physical set or model look just as bad as full CGI.

I saw only one of the prequels, 15 years ago, so these are clearly not part of my world. That said; What little I remember about the pointless story, the terrible writing, the terrible acting, and the equally terrible presentation still leaves me scratching my head at how the last three films have such a devoted following.

To read the thoughts of fans, all I can think is the films must have caught them when they were young and impressionable. The prequel story isn't deep, it's not thought provoking, nor is it even remotely interesting (the one I saw). Yet the members on other boards speak of these things as if they're Casablanca or Citizen Kane. I cannot make sense of that.
