Probably the most enjoyable shonen I've ever watched. I am an absolute nerd for all things science, even though it's not what I'm studying. So, this really unlocked the little kid who wanted to go to space and the long-time enjoyment of learning in me, as silly as that sounds. I genuinely adored the plot and can't wait to watch the last part with my friend next year. I loved the progression, the silliness sprinkled in among the stakes and scientific explanations. It's not my favorite of all time; my favorite holds a very special place in my heart. BUT! This is definitely a top 3 for me. Loved it with all my heart and will definitely be a long standing interest of mine!
