Very bad editing! No continuation or sequence followed for scenes. Music felt same as Enthiran. Like background score for chitti, Vaseegaran's lab and 2.0 were the same as Enthiran and likewise in many scenes. A.R Rehman's work could only be seen in 2 songs. Highly disappointed by music. Coming to the script I wanted to ask Shankar, why was he in so much hurry to end the movie? No background for the upcoming scenes? Just abruptly begin and end the scene just like the movie.The movie actually felt like a trailer, randomly throw scenes without any background and at the end of it throw another teaser(3.0). When you are making a 540 crore movie, then you could have bought additional 30 minutes to slowly progress the story and make it more logical and meaningful.
