As an audience, I found loopholes from the very beginning. It's really hard to believe having a movie in 2020 with that many loopholes and unnecessary storylines.
Addition to that, direction was poorly done that Leading Characters couldn't make enough impact on me.
Jacqueline seems to me a bit lost in the movie as her acting wasn't on point to justify her character, may be again the point poor direction comes.
Though the motive or the story of serial killer was interesting, could have been a great movie with proper direction, script and role play. It was so surprising to see how it's really easy to defeat a taekwondo black belt in such way, get a body and transform it to whatever body she wants. A person who has never hurt anyone before, so ridiculous to see her doing all those crimes without any hesitation.
