Watched Robot Dreams, going in with no expectations, thinking it'd be corny. It's a 2D animation with no dialogue and a cartoon art style. Supposedly it's filled with references to early New York. First day after watching it, I thought it was so so sad. Then the second day, I thought it was happy. I don't think it's a must-watch, but it kinda wrecked me and I'm glad it exists.

I think, it's a bit of a testament to non-verbal communication.
