Bad Bangla acsent. They way people talked here in this movie, Bangladeshi people don't talk like this. This movie's bangla acsents are from kolkata. Somewhere it feels like slow dialogue delivery. The Bangladeshi drug lord doesn't look like a drug lord, more like a thief. They should have cast some good Bangla acsent actors. The army, rab etc overacted everywhere. I think they didn't cast because of budget issue.
