As I watched “Isle of Dogs” (2018), I was reminded how much I used to enjoy “Samurai Jack.” There’s a zen-like inner calmness at the center of these two pieces of Japanese-flavored animation that I savored. This film is loaded with metaphors for all kinds of stuff I didn’t have time to try to discern (it’s a dark story about the potential for a doggie holocaust, and there’s heavy – perhaps too heavy – political symbolism). I was too busy either trying to make out the tiny writing on my normal-human-sized television or I was simply enjoying the calm, deliberate, confident storytelling.
