So far I like it a lot. I expected something much worse given my general impression of Japanese television dramas. Honoka is a good character, well acted. The show is at its finest when she is on the screen. Clearly the actress has put much work into practising and studying sumo. There is definitely some overacting from others, though I sometimes enjoyed this. The bodybuilder is the only one whose acting, or writing, borders on the genuinely bad. But he is supposed to be a stupid character... As an ensemble I can see the characters working and developing well. It's going to be unapologetically a feel-good story, but I'm fine with that. The return of a few actors from the film are also a welcome delight.
The only really annoying aspect is the music!
