I've only seen three of the movies listed:
- Avatar
- District 9
- Inglorious Bastards
I really loved Inglorious Bastards. I liked District 9.
But Avatar really rocked. No, its story wasn't anything spectacular. But it's visuals were. They have build a rich, detailed world with an immense beauty, and they created visual effects for it that made it feel "real enough".
I do remember when the Startrek franchise switched from modelwork to CGI (I think it happened either during or with Voyager) - I could see the difference, not always, but often enough. The Star Wars prequels might have been spectacular, but the CGI was impossible to miss. Avatar is the first movie that managed create an immersive experience in its CGI.. I am sure with time even that can be improved one and I might learn to see the difference (better), but at this point, it is a new level achieved.
