To go a little bit further on this argument: I was dissapointed because the whole point of making this film turned out to be for nothing.

Instead of animation, it felt to me like just a live action film with a fiter. Sure, the filter in this case took many man-hours to produce, and as stills felt pretty, but there was something vital missing.

I found this hard to put into words, but here goes:

Actual animation thinks about how to present perspective, movement, character, etc. This film chose to paint over moving pictures, and in that way literally took over all the 'real' visual elements without making any choices in them. Compared to almost any anime, it feels lifeless and an under-use of the medium, IMO.
