Its Abhishek Kapoor's right move for igniting this generation "rock-youth" and he envisaged his skilled for resolving the way of jeopardized situation of the band--"Magik". Shankar-Ehsaan-Loy's music is time testing too and its every beat, I think, vibrates/knocks every open-minded heart.
Farhan Akhtar, Arjun Rampal, Purab Kohli, Luke Kenny, Prachi Desai and Shahana Goswami -- all perform well and their gesture-posture proved that too in the movie. But, I feel personally, that Purab kohli is so called "Killer Drummer" in the movie as he did not show up his skill of exchanging drum sticks in air ( what he promised to Joe's son).
Though the concept as well as performances are very good, but presentation and sequences of the motion could have been made better. Still, to sum up, I must say that yeah thats right job done by all and its watchable for all.
After a long time, we got a new generation movie, so don't miss it.
