The overall show is good to watch. The fights are in some cases is good where a hero and a villain posses equal powers. But the one punch man character is too powerful that no one can compete him which makes a fight less interesting. You will not that he is going to kill a monster with a single punch. Personally, I like the fight where both the opponents have equal power better even a villain contains more than it will be a challenge to a hero for unlock his more power but in this anime case. How big or powerful a villain is he can't bear Saitama's one punch.
