While Superman is flying? Flash can't run forever. Eventually he's going to have to stop somewhere rest and eat. He better spend the rest of his life hiding in a lead line bunker.

What's hilarious is that Superman is now being used as a punching bag of the DC universe. Everyone and their grandmothers can beat him up. The biggest joke ever told, was that Batman could beat Superman in a fight. I get it, people love Batman and they hate Superman. Blablabla.. People are like if you give Batman enough time he can beat anyone. Lol. Let's be realistic. At any particular point in time Supes can pick him up and launch him into outer space and there would be nothing he could do about it.

The show got great reviews here in North America. It's got 99% rotten tomatoes and 8.9 on IMDB. If viewership is low, it might be due to the language barrier and/or genre. Maybe people don't like samurai shows.
