I think this movie isn't all that bad, it's worth the watch, but I must say. Its not exactly what you will be expecting. The movie will keep you guessing, confused, and trying to figure out what's happening, and wondering if it can be fixed. The ending, was definitely a "wtf" moment, and perhaps a bit underwhelming, but the movie was meant to go for that emptiness. Considering the Korean name of the movie is disappeared time, and that's exactly what the ending makes you feel. Which isnt necessarily a bad thing, but what I will say, leaves you questioning what happened even after the movie ended. It was interestingly put, and a different type of ending than I was expecting, and I don't necessarily hate it for that. I just want to say if you're considering watching this, lower your expectations, and don't expect anything, don't assume, just watch, and let the movie be itself, for everything it is and everything it isn't.
