I had no idea what to expect from this one - an R-rated animated feature?? - but I wound up really liking it. The animation itself was the first thing that impressed me - the rendering of textiles, especially, was just amazing. The writing was clever and funny and touching and weird, and the plot and world-building just became more and more complex and thought-provoking as the movie went on. The voice actors were good, and David Thewlis especially was perfect for the role. Just a satisfying viewing experience all around.
Also, when Dan Harmon's name came onscreen in the end credits, everyone GASPED.
Availability: In some theaters.
Animated Feature Film: Sure. Really impressive art, good writing, interesting philosophical points.
