48 fps trailer looked weird to me, so no thanks, maybe on a matinee or something but I don't really care.
But 2d versus 3d is not even a question. 3d is garbage. It makes terrible movies like Avatar even worse and detracts from what would otherwise be good movies. If it's overdone it's annoying and if it's subtle I have to ask, what was the point in the first place?
So if it's not throwing it in your face, it's pointless?
Subtle 3D is the best 3D. Like Avatar's 3D. It wasn't a spectacular movie by any other means, but it is a landmark 3D film. Why? Because it was entirely about the subtle 3D effect, with in your face moments simply there to demonstrate 3D for the feeble ones among us.
Subtle 3D is entirely about the presentation of added depth to scenes. It helps presents a spatial foreground, focal point, and background. If you are in a good position in relation to the screen, it literally looks like one is staring out a very real window. While you can't control the focal point of the lens (like in real life with your eye), you still get the effect of that screen seemingly melting away, and being presented with a tangible foreground and background of the scene. Instead of puzzling your mind to see depth displayed on a 2D projection screen, you instead see a realized scene that extends in front of and beyond the flat screen.
Subtle is best, imho. I don't need "oh wow it just jumped out at me!" 3D, that's just gimmicky. But added immersion with a very real sense of depth? Yes please.
Is it perfect? Hell no. But I'll take it, at least until we can get visuals pumped directly into our brain/optic nerve and skip the whole "looking at a screen in front of our eyes" thing. True 3D holographic visuals might be the next stop-gap measure toward my personal dream, but we're still a little ways out from that even, let alone doing anything that skips the retina (or at least does a new trick in regards to presenting visuals to the retina, unlike anything we have at this time).
