I LOVE IT!!! and would very much want to have another sequel! The 3 minutes episodes highlighted each scene in the story and made the watching time really quick, the actors portrayed their characters nicely and made quite an undeniable chemistry (also they're very good-looking). I would also like to commend the fight scenes which was very good and has the right amount of intensity to it, the visual effects and music was just fine, setting was also alright, wardrobe is okay, overall... for me, it's good.
Now, on the other side, the shortness of the episodes kind of deducted some points on the story, the small count of casts are also noticeable, scene change isn't that smooth, shot framing are sometimes not appropriate and few more others. It's all fine for me though... I'll surely rewatch this over and over again.
