It's definitely a miss or a hit (tho not a big hit). Don't go into it expecting much from the movie. I guess I could only continue bc I've seen a few words from a review here which said that it's "indie", and going into it knowing that made me finish it and appreciate the weirdness. So if you pressed start without any warning you may have closed it already. But looking at it with the indie-glasses, it's actually cute and fun. A slice-of-vampire-life if you will.
If you only watch quality stuff and see anything else as a waste of time, this is not for you. But if you wanna see more of Song Kang's beautiful face and are okay with a bit of weirdness/cringiness/over-the-topness, go ahead, you might find it fun.
