Not every movie has to change your life, but some can’t even keep you awake. Duplicity is one of those. It tries to sell itself as a thought-provoking thriller, but all it delivers is a series of flat, soulless scenes that fail to engage or move you. The overall feeling is like watching one of those lazy Sunday afternoon TV movies, but without the unintentional charm they sometimes have. Everything here is dull, predictable, and poorly executed. The script lacks punch, and the actors don’t seem to believe a word they’re saying. Sure, there are plot twists, but they arrive either too late or too clumsily, and instead of surprising, they confuse—or worse, bore. If someone recommends this film to you, be suspicious: either they have really strange taste, or they secretly dislike you. It's hard to find anything redeemable here. Even being generous, it barely qualifies as background noise. And that’s if you have a fever and can’t find the remote. In short, one of those films you forget before the credits even finish rolling.

I wish my wife would stop believing that Tyler Perry movies are good.

you know when you REALLY want the movie to be good and you're just watching hoping it becomes good and it never does? that's this movie. the story could have been greatly used but it was just a blob of very badly written lines and soapy scenes ... I don't know, it's just bad.

He produces numerous titles quickly, but none are worth watching. The plot and storytelling are lacking. Don't waste your time.
