Video: I mean, the animator in the gif above changes his shirt at least four times before he's able to make the Ninja Monkey doll walk, like, a couple of steps. That's a lot of time spent animating the most basic of motions lasting just seconds. Imagine all the elbow grease that goes into the more intense stuff, or even a minute of footage. In the behind-the-scenes footage of Kubo and the Two Strings, we get to see a bit of the magic that goes into making a stop motion film.
I didn't get a chance to see the film yet but, given its masterful blend of stop-motion, computer animation and still life, I'd probably watch it regardless of plot.
