I had lofty expectations for this episode, but somehow MADHOUSE exceeded all of them.
Fucking incredible. The animation blew my mind. Meteoric Burst holy shit.
They even managed to improve on the source material in parts. The fact that Boros and Saitama were kindred souls was emphasized fantastically.
For real though, the climax was bloody amazing. The music swells as Saitama finally goes on the offensive... but it's almost as if the music is meant for Boros instead. HE is the one finally living his dream. HE is experiencing what Saitama longs most for. HE is the hero fighting against impossible odds. The fire in his eyes. The very same beating of his heart. He pores all of that rekindled passion into one final attack.
Then the calm after. Both parties lie to themselves and to each other that the fight was fulfilling and worthwhile. But not for long. The reality sets in that it was never a fight at all. Boros dies with a bittersweet taste on his lips, and Saitama once again walks away from a fight unfulfilled, hopes dashed. But this time he walks away with the knowledge that, by extension, perhaps no one in the universe can offer what he wants.
It was surprisingly touching.
Alright, I'm done waxing poetic. But damn I really enjoyed that.
