tldr: WATCH IT UNTIL THE FIRST HALF OF THE THIRTEENTH EPISODE. Unless you can stomach bad writing, then watch the whole thing.
I loved thus show up until the 12th/ 13th episode, up to the point that it was the best for me. I thought the series could've ended right when it started with its already packed plot but it kept getting better and better. Everything was unexpected and each episode had me wanting to watch more. The mystery, action, and even the romance got me hooked . Fast forward to the last episodes, everything felt redundant. They showed an "ending", scrapped it, and proceeded with a substandard plot that was just... bad. Plot holes became abundant; Character developments fell apart; It was just a cringe fest over all. Wish they ended it earlier, it would've been perfect.
