/> Cast: Ranbir Kapoor, Nargis Fakhri and Moufid Aziz

Director: Imtiaz Ali

Rating: ***

Jim Morrison once said, 'Film spectators are quiet vampires'... and in case you are planning to catch his self-confessed disciple Janardan ‘Rockstar' Jakhar (Ranbir Kapoor) in action this weekend, you are in for a feast.

In Imtiaz Ali's most complex project till date, Ranbir has delivered a performance which hardly any of his competition can hope to emulate. From being a downtown North Dilli boy JJ to an angry and bitter Jordan, he makes up for all the holes you can pick in Imtiaz Ali's plot with his brilliant histrionics.

Yup, Ali's Rockstar lacks depth... just like its protagonist Janardan's life. With a hairdo and clothes that resemble the fashion of the early 1970s, Janardan, or JJ as he calls himself, is constantly trying to ape rockstar Jim Morrison and is constantly seeking a formula to become one.

His confidants, college mates and college canteen owner Kattara Bhai tell him that to be a rockstar one needs to experience life altering love, heartbreak and self discovery. And his mind ticks till he spots Heer (Nargis Fakhri).

Heer is the diva of the college, poised and polished very lady like. Their union seems unfeasible. After a few scenes, we learn that she is to be married off within 20 days and wants to experience all that is forbidden.

The duo makes a list and bond over soft-porn cinema in a seedy Delhi theatre and country liquor but without emotions for each other. In due course, JJ is christened Jordan, which seems to be an apt name for a rockstar.

As the mystery unfolds over layers of flashbacks, it takes the story to a designated plateau and halts.

At stages, you feel you are watching a documentary, full of montages of memories lined up over good music. Be it Sufi music or the shehnai-guitar jugalbandi, A.R. Rahman's music touches your heart.

Performances are superb. Nargis is a sure threat to Katrina Kaif. Shammi Kapoor sharing screen space with Ranbir touches a raw nerve. Over all, Ranbir carries away accolades for his histrionics.

Coming from a director who has given wonderful hits like "Jab We Met" and "Love Aaj Kal", "Rockstar" fails to match the hype. It's evident that there is something amiss with the characterisation of this love story.

During the entire transition it is not revealed how Jordan becomes a symbol of rage nor does it reveal the 'junoon' of Nargis' character. But even Imtiaz Ali's non-linear and jerky story telling can't eclipse the rise of a Rockstar.

With some beautiful wide angle shots, the film captures scenic Kashmir, Prague and Delhi in a way that has not been seen in the recent past.

The editing too is crisp but the last half hour is agonisingly similar to Shahid Kapoor's "Mausam". It just goes on and on.

The dialogues are refreshingly rustic and funny. An extra star in the rating for Ranbir's performance. He along with AR Rahman's stellar music makes ‘Rockstar' a great one-time watch.
