I've had this discussion with many people. I enjoyed the movie for it's technical merits, not the plot.
I saw both versions.
I don't get hte "3d headache" - but I definitely enjoyed the 2d version more. THere was more detail to focus on, and in tha tmovie, detail was everything. With the 3d version, I found myself trying to look at things in the foreground/background, and I just couldn't - not becuuse of any defect in my ability to manipulate my eyes, but because (I think...) they actually used differnet depth of field settings when rendering the 2 versions.. there were things in the 3d version you literally COULDNT focus on - they wanted your eyes on the action only. That buged me.
- I remember playing 3d Quake (the original) on my crappy home monitor, with LCD shutter glasses - and it was AWESOME FUN. SCARY.
So I think all the points in the article are valid, 3d is hard, for more reasons than joe average might know, I certainly learned some stuff - but it's definitely a aprt of the future, if only because our current equipment makes it technically easy to play back.
