I was completely disappointed after seeing the season-2. Story depth, build-up, details, explanation, motive more or less everything was lacking. Over predictable story. It seemed that they could have made it somehow and released it. After a while, I didn't understand where the black masked ninja was coming from. I don't know if they are monsters or people.
The only positive aspect is the fighting scenario .
The finish looked like another season might be on the way.
Personal rating: 5/10
