Quote: "Bad sets can ruin films too, this has been happening long before CGI and its kind of the same problem.
If I feel an outdoor location is actually an indoor set then the whole scene/film is almost ruined for me, or it takes away the immersion somewhat."
Ha, yes... reminds me of those old Hitchcock films, especially North by Northwest. It's really irritating when you can tell that the horizon is just 10 meters away during a scene.
Generally I personally like CG effects as long as they're helping the overall experience instead of being a central part of the film (as might be the case with Transformers or Avatar).
But then again... movies like Children of Men demonstrate that you can achieve pretty incredible cinematography, even in action scenes, with very little to no use of CGI. Each and every Tarantino movie is an example that you can create highly entertaining flicks without any CGI whatsoever.
Life of Pi on the other hand is an example of a movie with stunning cinematography that for the most part wouldn't have been possible without CGI. Same for films such as 300 or Sin City. Different styles obviously, but very nice too look at and it suits the narration. And imagine Lord of the Rings with an actor dressed up as gollum (well, that might actually work.. kind of hard to say).
So to come to the point.. I'm glad that we've got CGI these days, because otherwise we would have missed out on a lot of really great films. Still it's good to know that there are certain directors, even today, who make good, old-fashioned CGI-less 2D movies with actual film cameras.
