Mr. Ratnam is a dynamic, natural filmmaker who happily uses every device at his disposal, from rapid-fire MTV editing to sped-up action scenes that recall silent serials, to keep his lengthy film moving at a brisk pace. The film flags only when Mr. Ratnam must turn his attention to the soggy romantic subplots.

Well worth a look, despite its flaws.

Ratnam, known for integrating controversial cultural and political themes into popular melodramas, bundles a multitude of coming-of-age traumas into the kind of juicy, overwrought narrative that was once a Hollywood staple.

Though director Ratnam keeps this actioner running MTV-smoothly, his global pop style is both complemented and bested by composer A.R. Rahman (Lagaan, Bombay Dreams), whose electronic soundtrack grafts chunky post-hip-hop beats onto the quickly evolving sonic norms of subcontinental cinema.
