1 star just for Prithviraj's hard work (not necessarily acting). Simply put it's a disappointing and massive injustice to the Novel. A very poor attempt to showcase it as a global level survivor movie but miserably failing in doing so. Unnecessarily slow paced, filled with annoying and repetitive acting sequences and background scores.
Similar to the actor you will be equally trying to escape the movie theatre after an hour of patient watch.
Don't do the mistake of falling for the 5 star reviews and end up in a theatre. Just wait for the OTT release and you will thank all those 1 star reviews later.
