The most hyped movie in Tamil Film Industry for the past two years. It was hyped because it was to be hyped as such. Forget about the logic, forget about to story telling and creative thinking. Just sit back and relax for three hours and enjoy the movie. Since you will not watch this movie if any other actors have done the lead part.
The movie has to be watched one and only for Rajni Kanth's performance and style. Initially it was extremely doubted how Shreya could be a joint for Rajni Kanth. But Shankar's idea was not wrong, they had a very good Chemistry if you do not think Rajni Kanth is in his 60,s and Shreya's in 24 or something in their age.
Coming to direction and the story part. Shankar seems to be totally confused about the story plot, the way he crafted it. A confused climax. In the previous movies of Shankar the message is the one drives the whole movie, where as in Sivaji. The message comes in the climax that Rajni did all this to remove the black money in the country and yet to see that poorer are still poor. You need to watch closely at the end of the climax you still see people selling cows in village tradition using a money card. The message comes at last so that you wont find a clue about the complete mis direction of the story that they were not able to find a way how to end the movie.
Music - Yet another A.R. Rahman's midas touch.
Special Effects - Well done K.V. Anand who has worked for one year to complete the STYLE song. Heard it is a DV Technology and nothing to do with the Graphics.
Stunt Choreography - In the climax fight,it was showed Rajni's going to fly like as in Matrix but its just nothing. Too many longer fight scenes without any good cause could have made them shorter.
A lot of hard work has been done. Could have come better if Rajni Kanth's talent have been employed properly.
Overall a must watch Rajni Kanth;s movie I give a 8/10 because of Rajni Kanth.
