I watched the Blu-ray version of "Knowing" the other night.
That was some good workout for my subs.
Picture quality: excellent. Great details and colors. But the CGI effects suck.
Audio quality: excellent. Magnificent music soundtrack. Best part for me.
Special features: so, so. Not much there to bite. Boring would be the word.
Story line: very simple, maybe too much so, seems like deja vu.
Acting: also very simple, nothing to get an Oscar for, that's for sure. Low Fi.
Overall: a great rental for your audio system and display.
Final verdict: 3.5 out of 5 (mainly for the video and audio parts).
