'Decoding Annie Parker' does make for difficult viewing given the obvious nature of events, but the film tells the story of Annie Parker in a rather elegant manner. Samantha Morton is outstanding as Annie, she portrays the character to perfection and takes you on a journey - great performance. Aaron Paul is very good too, as he plays the role of Paul. The rest of the cast are solid. This production is pretty straightforward, not that that's a negative as it prioritises storytelling and allows the actors to act. It was also the right call to make the run time 91 minutes, any longer then it would've dragged. My only criticism would be that the two onscreen narratives never join up, I was waiting for the vast majority for them to collide but they never do; barring one conversation. I guess it's sticking to realism, though. Overall, a fine film.
