What the hell did I just watch? Am I drunk or is that an incredibly surreal movie? (answer: I'm definitely drunk)

Is no-face good or bad? Or just bad under certain conditions? How did Ja Hiro figure out that Haku is a river?! Why are there sentient frogs and also frog-people in the same universe? WHAT IS HAPPENING?

ETA: I tried to insert a picture but it seems to have been Kinja'd so I added another one

ETA again/update: In my slight intoxication last night I seem to have left out how very much I enjoyed the movie. It was great! Just a bit confusing, haha.
