The direction and fights are nothing special, lots of quick cuts and awkward edits but it's your usual action shtick. The story is a little too farfetched at points but it's an Asian drama so that's to be expected, the moments between the sisters are pretty damn adorable and wholesome and I wish they'd gotten more screen time together because their differences are far and away the most engaging parts of the movie. The big bad of the movie is laughable and so evil it's almost cartoonish but again, it's an Asian drama. All in all, it'll entertain you and it's not the worst way to kill time, plus it's just over 90 minutes which is a plus in my book! I haven't read the webtoon is based on so your experience might differ if you have.
