I like 3D movies. I find that 3D does add something to a film. It makes me feel like I’m actually in a place. It makes me feel that I am actually looking at the characters. Ever notice that a photo of someone sometimes seems really different from when you see them in person? Part of that is the loss of depth in the photo.
Of course, if it is “fake 3D”—added in post-production rather than actually shooting with a pair of cameras—then there’s really no point. Like anything, if it’s reduced to a bullet-point check-box to make some executive happy, there’s no point. Not every film should be 3D. Some films exploit 2D. For those, 3D isn’t appropriate. 3D can cause headaches and other problems for some people, so that is something to consider too. I’m also not a fan of most gimmicky 3D shots either. A film could take advantage of 3D to create a shot you couldn’t do in 2D, but—in general—just adding 3D to regular shots is what I like to see.
Yes, 3D is dimmer than 2D. That, however, is fixable. Even with it, though, I find that the 3D experience makes up for it.
Of course, 3D isn’t necessary to make a good film. A lot of things aren’t necessary. Give Scorsese a flip camera and a shoe-string budget, and he’ll probably still make a Scorsese film. That it isn’t necessary isn’t an argument against it. If you don’t find that it adds anything, then—yes—it is extraneous...for you, but that is a matter of opinion.
I think 3D also increases the imperative to move movies up to a decent frame-rate. That’s something that should’ve been done for all movies by now.
Yeah, theaters are using 3D as an excuse to charge even more. I’m fine with that. 3D gives me a reason to go to a theatre, because I’m not going to get a comparable 3D experience at home any time soon. It’s a value-add, and I’m willing to pay for it. It’s better than a lot of the other ways theaters have and could try to make it in the tough spot they’ve been put into.
