Rock on made me Nostalgic. The good old college days and moreover the drive to make music. Rock On! manages to engage you with a simple story of a rock band. How the Band forms, separates due to differences among its members and how they reunite. It is a feel good movie and worth a watch. I would rate this movie 7/10. Somethings that could have been "much much better": Music - Good songs but not great, been experimenting a lot these days with upcoming rock artist in India like Raghu Dixit and found that rock-on missed out making great "hindi rock" numbers. Reminded me about Dil Chahata Hai too many times. One friend who is also comical and easy-to-go patches up two other friends after many years. And many other instances. Characterization of some key characters were Weak. Rob & Joe in particular. How it reminds me of my jamming days at Orange Pale for almost 3 years. The last year in college the band lost some key members and I had to end up singing and manage with a 3 member team. I write much lesser these days and don't compose music anymore. Rock On sure rings a bell!
