Every story has a protagonist, who is posed with a challenge and ends up in a conflict; later the conflict reaches a threshold when the protagonist takes action and finds a solution. All the three elements, protagonist, conflict and the solution, decide the flavor of the story. There are audience who wouldn't mind the solution part being idealistic, because idealism carries entertainment; but there are audience, who wouldn't appreciate an ideal solution, especially when the conflict part is utmost real. And that's where RGV's Rann fails. It has a very realistic conflict; but the culmination is foolish and stupid. All the build-up he gives to the theme and story fizzle out because of the idealistic climax.
One can never stop noticing Amitabh Bachchan uttering 'mera beta' like he did in Sarkar Raj. The flow of tears from his eyes haven't stopped since that film. It's as if Abhishek Bachchan died in that film, just to be re-born as Sudheep in this film; but bloody hell, just to die here again!!! Sudheep, inspite of over-scratching his nose and forehead, impresses with his awesome screen-presence. None of the cast perform badly, but they hardly rise above the mediocre, single-expression characterizations.
The most laughable aspect of this film is the BGM. I sincerely doubt if the re-recording sessions were attended by the director. The tone is similar to that used since Sarkar, it's hard to ignore the carelessness in placing the compositions along the run of the film.
Another aspect, Cinematography, though not laughable, was mis-utilized in the film. The execution gets restless right from the beginning of the film; the camera shakes as if the audience should get drunk while watching the film. The shake would make sense had the usage been restricted to crucial situations, mostly with respect to Sudheep's struggles at various points of the story.
Anyway, just to conclude this crap, the film would seem entertaining to those people who hardly care about the crap I mentioned above. But a sensible climax would have given this film more value.
