First Hit: At times funny but it became more ridiculous as the story progressed.
The setup is that Jeff and Karen Gaffney (Zach Galifianakis and Isla Fisher), with their children, are a happy well-adjusted family in suburbia. He’s a human resources manager at a large company that employees much of the town. She’s a bathroom designer. Their boys have been sent to camp for the summer. An empty house near theirs is sold to the Joneses, Tim and Natalie (Jon Hamm and Gal Gadot respectively). From the beginning Karen suspects the Joneses are a bit odd and through some funny investigation, discovers they might possibly be spies.
The Gaffney’s continue their growing friendly relationship with the Joneses but their caution is rewarded and eventually the Gaffney's learn the truth about the Joneses. The rest of the film is how they team up to find out who, in Jeff’s company, is selling microchips to the enemy.
There are truly some funny bits, but then these behaviors get over played deflating the point of the behavior in the first place. The action scenes are OK but the car chase (Mercedes and motorcycles) was too long and not believable.
Galifianakis is funny and his behaviors that make him funny tend to be repeated more than needed. Fisher’s character is more interesting than Galifianakis by being inquisitive and less predictable. Hamm was solid as the undercover spy that wants his life to change. Gadot’s character was a little over done for me. More humor from her would have helped. Patton Oswalt was funny enough as Scorpion the villain. Michael LeSieur wrote a partially funny script but behaviors in scenes were repetitive. Director Greg Mottola had good actors but a script that failed to expand the story and characters.
Overall: After watching the film, it is easily forgotten.
