Kids like the concept of a secret agent nowadays, especially with Hollywood portraying them as stealthy individuals with pockets fit to bursting with high-tech gizmos and gadgets and other paraphernalia to aid in breaking into a high-security compound to obtain information that can stop the villain's plot to take over the world.
When really all a spy does is wait and listen.
This movie isn't for a teenage or adult crowd, it's for children who'd be interested in this sort of thing. It's good for the imagination.
Unfortunately it's drawing way too much attention to itself from an older crowd who has seen previous movies in the franchise.
