I knew I'd see Homestar here sooner or later. Long live Strong Bad!
I'm going to comment again, just 'cause.
I'm glad you're talking about FCPX as it has supplanted Adobe as my daily driver, but the interface improvements are from 10.3, so maybe mention that. Oh, look, everyone else is commenting on this too. Oh well, here goes.
This was a really worthwhile way to spend a few hours. I had the feeling after the movie finished that I had seen something special and would like to see it again immediately. I don't get that feeling often.
I noticed there were some deliberately loud audio stings that for me in a regular theatre really increased the tension of some scenes, but in IMAX might have been simply unbearably loud.
