Yoga Hakwon (2009)

Well first me and my friend were watching this movie and we were all into it at the beginning and in the middle till the end things were just happening. Me and my friend were really confused about almost everything and still do not get the ending. I NEED AN ExPLANATION!!!!!!!!!!!!!!!!!!! Now!!! Please message me if you see it and get it. I have my own thoery but i need to know the actual one

Oh man, this movie is so ridiculous. I think the premise and the origin story of the yoga institute founder (which gets revealed in pieces throughout the film) could be sort of interesting, but it's all done in such a hammy way that it's more funny than scary. Most everything that happens in the second half of the film is totally confusing - not to be confused with oblique or mysterious, just sloppy and confusing. What does the confusing ending mean? It means that the writers got lazy!
