I've seen the short 4 times now and would definitely have a lot to say. I've always been more interested in doing a detailed breakdown of Prep & Landing, but I don't have a good screenshot source on that one. I also have a shorter than usual schedule for a project like this because I'm working in Ireland for a few more days.
Trying to think of the topical reference. I'm sure it's there, just don't remember it. Also, they've never established a time period for Frozen. It looks like Once Upon a Time in fairytale land, but I wonder if it could be an isolated kingdom in contemporary times.
If it was meant to prep us for Frozen 2 I'd say that backfired in a big way. Anti-frozen sentiment has never been so strong. I've also never been more impressed with Kristen Bell's singing, but she's still just working hard to keep up with Idina.
