1. Well to talk about positives, Prithviraj has bettered himself and acting was much more subtle than his usual over dramatic usual portrayal.
2. Cinematography and Background score was good.
3. Efforts taken by Prithviraj (Physical transformation) was great not sure if that can be taken as acting skills as now a days every actor does this.
Now the not so great aspects
1. Film was bit boring at times and songs were not up to the mark especially when it's A R Rahman we expected more.
2. Over emotional scenes are part and parcel of this movie, sometime it's too much over tolerable level.
3. Story seems a little weak and climax was more like done in a hurry.
4. Direction was not up to the mark , more than survival story it looks more like over emotional melodrama
Final Verdict : One time watchable and good movie. Nothing wow !
