The story was lacking in all regards. Unless an original plot is present for an investigation thriller movie, directors should stay away scripts. I can name 10 movies with the usual plot from the back of my head quite easily. I assure you 80 per cent of the audience who have not even watched the movie knows who the killer is or has doubts about that particular character being the killer.
Talking about the unnecessary scenes and slow motions , they degrade the movie in a whole new level. Unnecessary characters are being added. Actors who have great talent are left with roles which are not demanding enough.
People usually want to see talented actors given enough space to perform. Fahad Fazil's role in this movie can be done by any actor. Even if his character is absent throughout the movie, the story will move on.
Moving on to the music, apart from the first song, even the BGM is bad.
Talking about the cinematography. The usual style nothing special. Don't get why people are trying to hype up the movie when there is nothing good to it.
If you are trying to show a woman empowered movie, make it so that the main women characters have depth in it. Adding cheesy lines like "This is all it takes sister" doesn't do any good.
