First 4 episode is 2 or 3 stars, last 3 episodes 4 stars.
Pros:
1. Great animation and art style.
2. Amazing soundtrack.
3. Voice acting is overall good but not without issues. The acting is a bit over the top and a bit weird at times.
Cons:
1. Pacing is all over the place and alright plot. Story picks up at last 3 episode.
2. Character actions sometimes makes no sense. Often doing things for no other reason than the plot is written that way.
3. Potential lore breaking elements that need a lot of explaining and development in future seasons.
