Melissa McCarthy is her own worst enemy in "The Boss". Since she co-wrote the script and then hired husband Ben Falcone to direct she has to take the blame for every misstep and bad choice that is made, and believe me there are many on view.
If you tell someone else how they should feel, who they should love, what they should do, etc., you are telling them that their own experience, their own journey, their own path is pointless. Their unique existence? Meaningless.
