In the first ten minutes of Kunal Deshmukh’s second instalment of the “Jannat” series, the director sets up his principal characters, establishes a romance angle and even adds a song for good measure. He also manages to inject no originality or freshness in any of these facets of the film, with the result that “Jannat 2” never really takes off, maintaining a staid pace throughout its two-and-half-hour duration.
