I think it depends. Sometimes there might be some artistic liberties taken, but it could still be mostly based on real events.
The accuracy of a true story based on Kevin Hart can vary. Maybe some details were exaggerated or simplified for the sake of the narrative, but the core might be true.
It's hard to say for sure. True stories often get adapted and might not be 100% faithful. But it could have elements that are rooted in Kevin Hart's experiences.
