Post-conversion 3D where there weren't lidar maps made during filming is gimmicky.

Even Avatar 2 wasn't shot in real 3D, for the most part. (Of course, given it was mocaped and rendered.)

Live-shot 3D kind of sucks because you don't end up with enough data to do compositing correctly, and you can easily shoot things that end up with uncomfortable artifacts for the viewer that you can't fix after the fact.
