The 1st time I saw it, it seemed a little too long, but the 2nd time I saw it, I couldn't believe 2.5 hrs went by so quickly. The phrase is often thrown around haphazardly, ...but this film truly is "state-of-the-art". Simply amazing what they've been able to accomplish. Watching the screener on my computer was amazing enough, ...I can't wait to see this in IMAX.
