Step Brothers is a classic example of a cliche comedy as it follows all the steps to make a succesfull comedy firstly you have the fallout then the two men who i suppose are stuck in younger brains become friends and as they are having so much fun it all goes wrong when the dad and mum think that they need to be responsible after going through the film trying to get them to get jobs it is them who re-unite them and as they peform a powerfull ballad they all live happily ever after.
