This is a suprisingly good movie.
At first, it sets the scene, which was interesting, and then for the next 20-30 minutes kind of meandered into some forced dialogue which was making me question why I was watching this.
And then the action explosively kicked in, and I don't know if they replaced the writers mid-way through, but we find JLo in her element, witty, kickass.
The plot is familiar with no real bomb shells, and it's not going to win oscars.
But there is something about it that makes it worthy of watching for the entertainment (you've got to get past the first setup storyline) I would recommend this movie.
