This is more of a drama than a comedy. When Emma and Dave were arguing and Dave was saying that she needed to stop being an assassin to which Emma replied, "It's all I know," and then Dave said, "Take a class," that was funny, but for the most part, Kaley plays this so seriously that the little comedy there is doesn't work too well. The tone of it doesn't quite gel. And I never bought her in the role. She doesn't seem like a mum or an assassin. It never worked for me. It petered out to the end with a fight with the woman who was responsible for Emma being an assassin from a young age, but I feel like we needed a bit more of a backstory there to care. There are lots of better similar films. 2/5 at the most.
