I'll try to keep my review as short and spoiler free, and I suggest those who really really would like to read a review before watching the movie to only read this. The film is best experienced first hand, without any pre-notions.
I am really happy to be one of the very few people to watch the world premiere at the 25th IFFK at Thiruvananthapuram, and in one word the film could be explained as mind-blowing. This is not the ordinary Malayalam cinema, this is a whole new world of ideas. Since the movie has not yet been released to the public, let me just summarize it in this: Lijo does something really confusing that leaves us stuck. Apparently I feel that that was his aim too. He wants the viewers to be trapped in the spiral or Churuli he created. Each time you think about the movie, you find something new, and it again traps you in the whirlpool. And that concept is just wow, he did that perfectly. And I say this loud and clear, only malayalam industry could attempt such brave experiments. One of the best movie industries in the world.
Keep a special attention to the story said at the beginning (which is present in the trailer too), personally I felt that that was a fourth-wall breaking story. Yes, the audience are as much part of the film as the cast . As Lijo himself said: "This is not a Cinema, this is a Churuli(Spiral/Whirlpool)".
