This is an exceptional animated tribute by one animator, Chris Landreth, to another, Ryan Larkin, who he met at a rehab facility. 30 years ago, Ryan Larkin produced some of the most influential animated films of his time.
Chris Landreth made this animation video in a style he terms psychological realism. Which is a very good description. The style is about depicting the psychological realism vs. base material realism.
But even that’s not important. What is important is that this little short is…. unbearbly touching. I doubt you will see anything else today that can compare to this, or come close.
