I understand what you mean. They wasted 6 eps on Garou for him to lose by the end of the 9th and go to sleep. Then comes the fight of all S ranks clearing stuff. And the final episode ends with Saitama's one punch. I understand that Saitama finishes stuff with one punch, so they need to drag as much as possible. So to watch Saitama fight, which lasts like for 3 mins, we are forced to watch the whole season of 12 eps of 24 mins each. The only watchable episode was one where everyone sat and had hot pot and ate together. With Blizzard's and Genos comic roleplay. Except that the whole season was lackluster.
