Reposting from my review on Letterboxd;
Wow! That was quite a trip!
I'm glad that I didn't know too much about this film before going on aside from the occasional gif that's thrown around. The experience is so much better when you have no context before going in.
Also, was Inception inspired by this? It feels like it. Either way, if I'd seen this sooner, I'm pretty sure I would have become an animator instead of a filmmaker.
I love this film!
