For me it was “The Most Controversial Children’s Book in History” by Solar Sands, in which he analyzes The Giving Tree. It led me to think about my relationship with my parents, and about what kind of relationship I might have with my kids if I ever become a parent.
Everything by Patrick is great. His video on Speed Racer is so good. I love that movie so much. His Star Wars Christmas Special is what finally swayed me to subscribe to Nebula.
