Problems in the show,
1. Lack of background character's reactions to gore.
2. Long and annoying explanations about how magic works.
3. The Protagonist does things that pretty much break the logic of the show to the point where its a turn off.
4. Lack of overall knowledge of the world the show presents along with character histories.
There are a few more but those are just a few off the top of my head. I did enjoy the show but its a hit or miss for some people. I would recommend watching it.
