Naughty aka Juli Norwood’s review published on Letterboxd:
Gives a whole new meaning to the phrase "ROCK Your World"
Kim Ki-duk revisited similar themes that were present in his previous film Pieta! You would have thought the shock value would have been diminished considering we've "been there, done that!" But that was not the case! Not only did Kim Ki-duk whip the shit out of that dead horse... he brought it back to life! And like Pet Sematary the resurrected came back with a vengeance and were inherently much darker and more vile than anyone could comprehend! Such was the case with Moebius!
Kim Ki-duk managed to do MORE with far less! He eliminated dialogue altogether! This was a tremendous move on his part! It succeeded in creating a more visceral atmosphere! Jae-hyeon Jo, Eun-woo Lee and Young-ju Seo were able to tap into their respective primal natures and deliver performances of a lifetime!
Once again Ki-duk has taken a stab at being a masterful provocateur by delivering one of the most dysfunctional families to ever grace the big screen! Not for the squeamish or faint of heart!
When I wasn't clutching the arms of my recliner with a vise like grip, I was having a "severe case of the WTF's" for which there is no known cure!
