I saw this tonight. I really don't understand how people didn't see the 3D.
I thought it was really nice - subtle at times, but quite immersive. I have concluded most people who hated the 3D also just hated TPM, but perhaps I'm wrong.
Ditto that.
There were only a few moments I couldn't tell. Like long shots of the Naboo Cruiser in the Tatooine desert. But it always felt like it had a depth (usually 4 to 5 layers). I am starting to wonder if some of these theaters were just showing the regular but advertising it as 3D.
