Seems great, until that kid that's flicking popcorn or spilling their drink is now doing so from 40 feet overhead. Still, a movie-going experience that makes me feel like I'm in the Galactic Senate Chamber is tempting, and it'd make food/drink service far less disruptive for everyone else. The verticality makes me think we'll see a version of this in Hong Kong or Shanghai first.
Glad to see that Tron: Uprising will finally have the chance to reach a bigger audience, it's got a beautiful Aeon Flux meets abstract 3d art style and a stunning voice cast (Boxleitner, Elijah Wood, Tricia Helfer, Paul Reubens, Reginald VelJohnson), and expands on the world in clever and substantial ways, but languished on Disney XD. The story is strong, characters given surprising depth, and you could print and frame nearly any still from the entire show. If it took Tron: Legacy to birth Uprising, that surprisingly dull flick was all worth it.
If you're on a big enough production that camera wants timecode for sync but you like to run and gun or just don't have TC output, you can usually rent a Tentacle set for ~$20 and generate or jam-sync as needed. For projects where I am the whole sound team or times that I need maximum flexibility I like to roll with a Zoom H6 attached to the back of my boom by Superclamp, which acts as a nice counterbalance and means I can tweak levels in a take while holding the mic steady.
