Cristina, Yes we certainly agree that GF2 is a far superior film than GF3. But I believe that they have very different stories to tell.
In GF2, we see Michael's corrupt soul for what it is, but he doesn't. He feels that he is doing what needs to be done, and he doesn't fully grasp what the consequences are. In GF3, he undertands and is trying to redeem himself. And that is a vast difference.
