I started watching this one because of Park Bo Young, big fan of her work. Different character for her as this time she's not playing a timid character but a strong lawyer and she pulls it off well.

It's a fantasy, so you do need to somewhat leave your critical thinking mind at the door but there wasn't anything that made me just throw my arms in the air and go "but that's just utter nonsense" at all, it seemed like it was quite consistent with itself in a world that such an object might exist. I liked the presentation of it, the graphics and CG etc are done really well. The premise is also really interesting with the Abyss object and the powers it grants.

This one is difficult to fairly review without putting in spoilers, so I guess the non-spoiler summary of this one should answer the question - is this one worth watching. I'm going to say yes, but, be prepared for a less than satisfying ending.

The story goes really well until the end, and then suddenly it's over and you're left with the feeling of "what just happened". I re-watched the final episode again a second time because I was convinced that i'd missed something, but I hadnt, so it definitely feels like they took a 20 episode arc and put the final 5 in to the final episode of 16 episode arc, like it got cut short at the end.

I've seen commentary online that people feel the writer did a bad job because of the ending and honestly I don't agree, this one feels like it was out of the writers hands - the rest of the story stands up well, and it's because the rest of the story stands up that I'm happy to recommend this one. A good ending would have made it a solid 10 star for me.
