A native of Jharkhand settled in Kerala for 20 years, Durgaprasad considers himself more of a Malayali, though he feels sidelined often by the state. A doctors' strike at the government hospital forces him to take his wife in labour to a private hospital, and the shortage of money lands him in a few atypical situations.
Acha Din takes an unflinching look at the life of the impoverished non-Malayali workers in Kerala,whose fruits of toil contribute immensely to the state's economy. That's what the story begins as, though it ends up as quiet another.
Durgaprasad (Mammootty) and his wife Sheetal (Mansi Sharma) eloped from Jharkhand to Kerala as they drew the ire of the society, for marrying outside their castes. They have been settled in God's Own Country for almost 20 years and try to embrace it as their own, though the natives often consider them outsiders. Unforeseen events force Durga to borrow money from a terrorist for the medical expenses of his wife in labour. The story is about how he compensates for it, and does his bit for his foster State.
At a time when spotting a North Indian even in our villages is commonplace, the movie has made an appreciable attempt at presenting the community's woes, and the treatment dished out by the society to them. The aam aadmi played by Mammootty, however, soon metamorphoses into someone else, who single-handedly takes up a few mammoth and often unrealistic tasks for Kerala! The character is hardly challenging for the megastar and he pulls it off convincingly.
Debutante Mansi Sharma, who plays his wife also performs well. Padmaraj Ratheesh, who enacts the main villain, also proves to be the right pick for his part. However, for the kind of unrealistic story that the film says, the screenplay is weak, post interval and also drags towards being dull at certain points. What's expected to provide thrill doesn't, and it's also funny to see how the terrorists, whose apparently given training to withstand the torture by legal mechanisms, can't stand up to the punches of a common man.
Acha Din is fleetingly good, but it isn't a convincing thriller that it could have been. Watch it for Mammootty's common man avatar and also for his enjoyable explorations of Kochi on a bicycle.
