While not a terrible end to the series, I didn't like it as much as Divergent. I think I was hoping for a stronger finish, but it felt like the plot for bogged down in having a Tobias narrative and the GD/GP struggle. It almost felt like a repeat of Insurgent, but just swapping groups. 
 The series is still a good one, so I would happily recommend it to others who "like this sort of thing".
