Just saw the new 007 movie in IMAX... man i love that @#$%.... huge screen, great sound (real surround) and actually makes me enjoy films i might not have enjoyed in a regular setting =P Nothing beats the entire theatre actually shaking when explosions go off... err not much at least.
Dark Knight Rises was great in the MAX too.
Random, I know but if you havnt got the chance to watch a high octane action flic in IMAX go do it, its worth the extra 4$.
Also Directors hall is not worth the extra money!
