I agree with you that the film lacked substance and left us with the same questions we had with the other two installments.
I think it is simply part of this world, what was successful was in making us empathize with these protagonists. In the end I could say that I did like it.
Yes you're right. The protagonists ordeal was felt throughout the duration of the movie. It was emotional. Regardless of their flaws, its still a good movie to watch anytime. Thank you for stopping by. I appreciate your comment.
