IMAX films suck, by and large.

A vivid image of what should exist acts as a surrogate for reality. Pursuit of the image then prevents pursuit of the reality -- John K. Galbraith

Two random data points on 3D:

1. You can buy monitors with cross-polarised 3D technology (and glasses) for around double the price of a conventional monitor. I'm waiting to review on as soon as Zalman, who make it, release drivers for 3D Studio Max and make it useful for more than games and (as they put it) 'adult content.'

2. There are various no-glasses 3D systems in development - some interesting demos at a recent consumer electronics show. It's not consumer-level technology yet, but it will be soon.
