UPDATE: Slate magazine has a nice response called Two Thumbs, Two Dimensions.
Walter Murch is about as close as we in post-production will come to a rock star/Renaissance man. He’s a picture editor, sound editor, writer, technologist and thinker. He’s now somewhat of an anti-3Der and he lays out his case in a letter to film critic Roger Ebert. Here’s a tease:

But their eyes must converge at perhaps 10 feet away, then 60 feet, then 120 feet, and so on, depending on what the illusion is. So 3D films require us to focus at one distance and converge at another. And 600 million years of evolution has never presented this problem before. All iving things with eyes have always focused and converged at the same point.

The full letter is well worth a read and, with 3D movies hitting theaters seemingly every weekend, it’s a topic on which everyone has an option. You know what they say about opinions…

And speaking of Roger Ebert, his famed movie review show At the Movies returned to television this week as Ebert Presents At the Movies. If you don’t know the history of the show, and there is history there, then Wikipedia can educate you (Ebert, At the Movies). The important thing for movie fans is that the Thumbs returned to PBS this week, though they are different thumbs and the show’s got a bit of a different format. One thumb belongs to AP critic Christy Lemire and the other to mubi.com critic Ignatiy Vishnevetsky. Who? That was my reaction as well to this kid Ignatiy. You can check the PBS schedule to see when it’s airing in your area.

Here’s how the thumbs voted in their first week:

That’s a split vote if there ever was one! You’ll have to read on over at the Ebert Presents At the Movies website to see how each of the critics voted.
