Jen is defeated by the ostensible low point of Lindsay Lohan’s onscreen career, I Know Who Killed Me, while Tim cuts right through the Gordian knot that is the movie’s storyline. Also Jen vents her disappointment over a director she actually likes(?), sorta.
Someone actually tracked down the screenwriter, Jeff Hammond, and got him to open up a little about the production:
I avoided reading most of the reviews; however, it was impossible not to be aware of the negative consensus. I forced myself to read the ones that mentioned me by name (linked from Google notifications). That made for a handful of ugly reads. It’s a difficult thing for a writer to be accused in print of being tone-deaf.
His account is interesting, but there’s no revelatory info about the “themes” or “story,” because these things are about as one-dimensional as you might have guessed.
Charles Bramesco also made a case in the Guardian for the movie. You can probably chalk that up to personal preference more than a love of great cinema.
