Leaving out the grandeur that Mani ratnam brings to his movies through enriched characterisation and an abstract plot, there was nothing else about this movie that left a lasting impression. All actors did justice to the roles they were assigned (including simbu :P), with Prakash Raj single-handedly outperforming everyone else. This 'band of brothers' on-screen chemistry is definitely something to look forward to.
The background scores were pretty good, which is kind of expected from the maestro. And there's lots of "mass" moments which an average Tamil movie fan would definitely enjoy.
What was really disappointing was that an extremely tantalising premise was set at the end of the first half and the movie could've escalated to a whole new plane if they had not so whimpishly underplayed the big murder mystery. This took it from an gripping thriller to a filibuster.
Otherwise, it's a good one time watch, that keeps you engagaed throughout but fails to close well.
