The way the story is progressing tbh
And how is it "terrible"? Story progressing in best way it could:
1. Introduce Spade Kingdom, instead Diamond filler arc;
2. Introduce some strong members of Kira family;
3. Introduce whole demon group, which means that angels also will appear soon;
One thing that could be called bad was timeskip, but it wasn't that bad case characters didn't jump in power lvl.
So again what is bad for ya? ROFL
