I dont think its a 0/10, but it honestly is the worst in the current season. So far its a 3/10, and mostly because of the pacing, not the art.
You see, in a COMEDY, which this series is supposed to be, you need breather times to let jokes sink in, just like you need badass moments to linger in for a few seconds for people to appreciate it.
In the manga version of the sonic fight, we get some time to understand how fast the tenfold funeral illusions are, then an even greater moment of seeing Saitama making countless images. There are 3 full pages worth of saitama after images.
Then in the manga, we have more time to understand that Saitama beaten Sonic without touching him. He moved so quickly close to Sonic that the air around him created a shockwave and defeated Sonic.
Those details are lost when you make the whole scene last some 6 seconds instead of 15-20.
I dont know why they are trying to go so fast. The arc ahead is HUGE and they cant ever fit it in 12 episodes.
Why not focus on the Tournament sub-arc and leave the Hero academy and Garou as hooks for the third season? This way it would cover roughly the same as Season 1 did, about 7 volumes worth of story. I dont even know where JC wants to stop, because at the rhythm of 1 volume per episode, there isnt enough manga to last the whole season.
