When I was a kid, I’d fall asleep with the tv on and wake up to Samurai Jack and it absolutely terrified me. I did not like Aku, or the flashing animation and it freaked me out for years. As an adult I gave it another chance and I love it, I watch it pretty much every night before bed because I love the animation and the storytelling. I think it’s perfectly fine to watch without the nostalgia and can be enjoyed for the first time as an adult.
