This movie is about the life of 4 individuals who went through strange events because of their addiction to drugs.
All i can say is It gave me the creeps of all that just had happen to the characters at the end of the movie and thanks to the musical at the end of the movie it gave some edge to the climactic event in the film. People say that this film was not all about drugs, but understanding these 4 individual and how their life and dreams was been ruined so, If you want to watch a movie about drugs, I must say this one is for you because if you watch this film, you will definitely not see drugs as the same way as before. It's a good movie to watch but a depressing one though.
P.s
I so hated the mother. She so annoying, obsessed and delusional old lady.
I love the song nearly at the end its hauntingly beautiful.
I love the film making techniques they've used in the film.
