Indian cinema has never produced a true science fiction. We have always seen love stories or action movies in the disguise of sci fi. At the same time Indian audience loves Hollywood sci fi (matrix, avatar etc are hit in India). But, "Unmatta" is in different league altogether. It is one of the most brilliant science fictions I have seen recently. Criminals are committing suicides in jails. Police is baffled. We go a year back and a troubled student of literature (Aditi), gang-raped in childhood and suffering from sleep paralysis and PTSD, joins a telepathic experiment with four science students. What follows is epic journey into subconscious of each participant. Who is killing criminals? Can Aditi remember her rapists, and can she take her revenge? What does revenge even mean in an already mirage world! To get all the answers, one must be very attentive (not to miss single dialogue) till the end. Even then, I had to see it again to understand it fully. "Unmatta" can very well be most complex movie ever produced in India. Movie touches too many concepts in too little time (108 minutes!). Concept of dream being wish fulfilling entity, sleep paralysis, Post Traumatic Amnesia, PTSD, parasomnia suicide, free will and even parallel worlds or world being just a sensory input with its interpretation are beautifully handled. No wonder many critics failed to even recognize what was being shown and were quick to mark it yet another loud sounding horror movie (which it is, if science is ignored). Even then, its far better horror movie with lot of excellent action sequences. Such movie is rare gem. I hope it would have come from big budget production but then it would not have been so good isn't it?
