I didn't see it on Imax but, I really liked it. Somewhat less techie than recent Bond flix, it was more like the old ones, a lot of chasing and shooting, with an over-the-top bad guy. Craig continues to be an excellent Bond and Javier Bardem was suitably pathetic and sociopathic as the villain, Silva. I don't expect much depth from a Bond flick, but I usually enjoy them if the mayhem works, and, in this case, it did. Fortunately, the audience was well behaved except for a few first row teens that needed to come and go every 30 seconds, but they were below my sightline in the stadium seating.
Sound was about average for a cineplex, nothing great, but considering the mainly run and shoot action, it was as good as it needed to be. Bond is 50 years old now and with a couple dozen movies, it certainly is the longest running franchise and, counting for inflation, by far the most profitable.
