Holy, this...is really, really good.
Why doesn't Japan use more middle aged protagonist? Mutta's an amazing compelling protagonist, and that the issues he faces hitting home so closely only serves to make his character all the more engaging. The last protag to really strike a chord with me like that was Kotetsu from T&B.
And the directing for the episode was really, really well done. Bravo to the production team. If this keeps up Space Bros will definitely be one for the books.
