Reception
Critical reception
The film received negative reviews from critics, criticising the script which was described as "poor" and "unimpressive", with positive comments about the background score and cinematography. Veeyen of Nowrunning.com rated the film 2 out of 5 and said, "The even sag that painfully persists throughout, the mindless gunshots and blood splatter and the sodden predictability together blow up this film beyond recognition. And no amount of crashing and crunching can salvage an entertainer from the massive debris that it leaves behind."" Raj Vikram of Metromatinee.com said, "Gangster proves to be a half baked, shoddily made and unimaginative film. Without a speck of novelty it ends up as a routine revenge drama devoid of thrills. Painfully paced and lacking in an engaging plot the film huffs and puffs into a disappointing end". Padmakumar of Malayala Manorama rated the film 1.5 out of 5 and concluded his review saying, "With all its thunderous background score, dramatic slow motions, white-skinned cons, wowing locations, flamboyant frames and sleek cars, the film never fails from disappointing you to the core." Tony Mathew, also from Malayala Manorama, gave the movie a negative review and said that "Gangster is a disaster". Ajin Krishna of Oneindia.in said, "The movie Gangster works only for its different style, performances, music, visuals and the engaging climax sequences. Rest is pretty much average." Sify.com's reviewer said, "Gangster is perhaps an act of impudence, with scant regard for the time and money of the viewer. It's not easy to sit through this boring film even for a hardcore Mammootty fan."
