Swimming With Sharks is a case where the puzzle pieces don't fit but we're just forcing them in place, mostly based on tropes.
We have the out of town intern, Lou, played by Kiernan Shipka. She's joining the team of Fountain Pictures, run by studio chief, Joyce Holt (Diane Kruger) who still must answer to the sickly owner of the company, Redmond (Donald Sutherland). And Lou has her menacing overseers, the guys running the intern pool Alex and Travis (Ross Butler and Thomas Dekker).
The meteoric rise of Lou, from her first placement right outside of Ms. Holt's office, to becoming Holt's essential right hand is similar in tone to Don Draper's history from Ms. Shipka's previous series "Mad Men." Only Lou is more unsavory than even the 1960s Ad Exec in ways that maybe even Don himself might raise an eyebrow over.
The problem is in all of the elements to do with these characters, what we would expect them to do and what we believe about them, based on what they have done. In many of these cases, characters do or state things that don't seem to fit who they are or what we believe they would likely do in that circumstance and that always spoils the narrative.
Most importantly, with the character of Lou, I expected her to have a plan for every possible contingent, based on how she had dreamed, since childhood, of being where she was and how she has arranged everything to get herself to the upper reaches of Hollywood.
There are some definite good moments for each actor throughout, but they get skewered by all of the unbelievable ones. Everybody here deserved better.
