Great disc...the audio was the first 24 bit track I've heard on Blu-ray and it was astounding. Great movie too until the last 5 minutes. I figured out the twist 15-20 minutes in and was under the impression that the film revealed it well before it actually did, so I was expecting a little more - the film really shoves your face in it once you know what's going on. I also thought the treatment of Tesla was more than a wee bit far-fetched, even considering what I've read about the man. Still, the film's well worth watching.
