Well I have to completely disagree - I got the R1 bluray release a few weeks ago and I think it looks and sounRAB stunning.
I did see it in the cinema some months back, but not in IMAX.
I did not find the switch in aspect ratios annoying at all...I was too busy admiring the clarity of the IMAX images - especially during the stunning opening robbery sequence.
In fact I enjoyed the film much more second time round.
I have a reasonable audio visual set up, a Sharp Aquos 37 inch TV, a 300 quid Yamaha sound system and a PS3. Nothing stunning, but I am happy with the results I get from it.
I can also be a bit of a perfectionist and like things to look and sound right, but I did not find this distracting at all, I think it's an excellent presentation.
