The basic story - plagerism and its consequences - was an interesting twist on a classic moral struggle. The "why he did it" was believable, as the desire to succeed and to be perceived as a success, is a temptation that is hard to resist, especially when the odds of getting caught cheating are slim-to-none. This part of the movie was compelling.
What didn't work was the portion of the film that dealt with the over-complication of another author supposedly reading this story as if he had written it himself. There was no "ah-ha" moment that followed in this storyline, and so, the pay-off was absent. The scenes with Dennis Quaid and Olivia Wilde seemed as if they were shot by a different director and cinematographer - almost jarring, as they take you out of the "real story". While you have to applaud the effort of the writer to make a clever script, this part could have been eliminated in its entirety.
Acting-wise: Bradley Cooper and Zoe Saldana are a gorgeous couple, and their on-screen chemistry was sexy and classy.
Ultimately, worth seeing. A great conversation-starter re ethics and consequences.
