Just now, I was like "the heck is Coco?!" - then I saw what category you had posted this in. WOW, it's gonna be hard getting used to the new title! Kinda neutral about how it sounds, but at least it's catchier than "Untitled film inspired by Dia De Los Muertos."
And YAY, it's coming in 2017! *___* I'd been angry with myself for spoiling myself so much on Inside Out, so I was disappointed that there wouldn't be original Pixar movies in the near future which I could enjoy unspoiled. Really looking forward to this.
The plot details actually don't sound appealing to me at all, though. But Pixar movies have a tendency to have boring descriptions; I'm not worried yet. I mean - it's Lee Unkrich. I'm still convinced Toy Story 3 is the greatest movie ever made.
Anyway, thanks for sharing, Luis!
EDIT: Oh, and tying into the running gag that's floating around on the net since Inside Out, I guess this one is now "what if ghosts had feelings?"
