Scumbalina’s review published on Letterboxd:
The Killer Butterfly has an elliptical quality that I'm always on the lookout for. A Quiet Place in the Korean Countryside. Death butterflies that lead you to poisoned refreshments offered by a most beautiful witch. Death/Eternity taunting like a drunk cartoon crow. Skeletons that may look funny but it's they who are laughing. An emotional fever pitch that causes a figure to free-fall between almost unrelated scenarios that reflect a particular mental state or delusion. Fantasy and reality overlap and just when you're sure that you're in the waking world something strange happens to force you to question the reality of the state you're in and any state you've ever been in.
