This was excellent – from the actors and their performances to the plot and action, the visual and special effects, like you can smell the budget! The ending was great, but it’s open, so I wonder what will happen… Also, the girl Hui Soo saved back in her old school… it was clear there was more to her but the revelation came too late – again, will there be a second season?? The build up to the grand finale was amazing, and the last two episodes got me on the edge of my seat, but I wish the showdown would have been even longer. But overall, this show was fantastic in my opinion.
