I predict that every movie will eventually be 3D, whether we want them
to or not.
Personally, Avatar was the first 3D film I saw since Disneyland, and I
wasn't impressed by the technology. It wasn't any better for showing
movies than watching them on a 2D screen.
Now, if you could walk around inside a 3D movie, /that/ would be cool -
though it would defeat the point of /watching/ a movie :)

Hey, that's pretty cool - I wonder what would happen if they upped the
jitter rate to something like 120fps?

Maybe it was not a masterpiece of scriptwriting, but I didn't find it
so absolutely horrendous.

It has only been 19 years since Terminator 2.

Interesting, I may just have to go see it in 3D in the cinema if that's
the case; I've heard rumour that projectors using DLP may be able to
handle some 3D projection (and I've got one), but this is starting to
intrigue me now.... :-)

From what I've read, there's a maximum speed you can jitter at, because
your brain has to process the picture and break it down into objects (which
happens about a third of the way along the visual path) before the scene
changes, or the effect goes away.
I.e., your eyes pipeline processing tremendously, with whole lots of stuff
being computed right in your retina (like outlines), and if you overwrite
that before it gets to the infront/behind processing, the effect vanishes.

Yes, that would be his 3rd best :)
(I realize that such a ranking is, by it's very nature, contentious...
but for me, Aliens was the best, with Terminator being second, followed
by T2 and Titanic, and then The Abyss. I have yet to see either True
Lies or Piranha 2, so I can't judge those).

There were many points during the movie where objects in the foreground were
blurry because of DoF, and if you tried to focus your eyes on them they
would look like a blurry object.
I don't consider this to be a serious flaw; it's more of an artistic
decision. Non-3D movies have exactly the same problem (focusing your eyes on
an object do not bring it into focus), and I don't think it matters much
more when viewed stereoscopically.

I mostly agree... though when you get cross eyed to look at a close object,
your eyes are used to get focus closer.
Here they are not able to...I got some trouble with that before accepting
it.
At other moments I enjoyed having (as IRL) small things as 'mosquitoes' or
seeds flying at the edge of my awareness between me and captivating action.
I thing it is a gimmick though, when got used to, it loses most of it
interest.

I disagree. Maybe it's just because we're more used to flat film (the same
way that video games put in stuff like lens flairs even when the character
isn't using lenses).
I think the brain knows it's looking at a projection on a flat screen and is
more fooled by the stereo, so the inability to focus is more obvious.
YMMV of course.

That's how a lot of tilt-shift images are able to give the impression that
the viewer is looking at animated toys, instead of a film or image sequence
of "real" objects. We have become accustomed to the subtle cue that a narrow
depth of field (a feature of macro type lenses) means we're looking at
something small. An artist can play with depth of field (as well as color
saturation and other goodies) and create an illusion based on our
acclimation to cinema and still photography. I once saw a guy do a pretty
good tilt-shift simulation artificially (layer after layer of abstraction
now...) in Poser of all things.
