At the beginning, it's great, but towards the end, it's horrifying.

The story and the concept were absolutely fantastic for me, and even the execution was interesting. The actors also delivered a good performance. I even managed to handle the main character, who seemed extremely whiny over time. However, the final episode completely ruined the whole series for me. It felt totally undeveloped and nonsensical, as if they needed to quickly wrap up the series and put together the ending during a lunch break. It's a shame; the series had the potential to be on the top charts.
