Visual Effects far outweigh the story telling and theatricality

Rating: 6/10 (28 May 2016)

Overall, I really enjoy the strong and fantastic visual effects, nevertheless I have some of questions:
1) What is the motivation of the followers of the "God". If the memory is eliminated from human after each return of the "God" to the earth, what makes the followers keeping on calling the "God" back; If not, why these followers insisting on calling back the "God" to restart the civilization by massive destruction, as the price is so huge.
2) why the "God" need to find teammates, seems he can easily control the human minds (a fact here is he fires all the nuclear to the sky through invading and control the mind of the soldiers)
3) the "God"'s intention is destroy the current civilization, seems firing all the nuclear weapons down to the earth is ten times enough to destroy the earth, why he is so stupid.
4) why the "God" is easily be betrayed. what is the motivation of his "teammates", seems not clearly presented.
5) finally, why the "God" is defeated without even sweat, a girl who overcomes her inner fear become the last straw of the "God", hard to accept.
6）I had thought our Magneto is a faithful men, but he had a bastard; and his bastard are eager but reluctant to tell him the truth.....why why why.....even in face of the destroy of the earth.
