I will see it and like it.
Because there are two types of audiences.
The die-hards, who will beat a film to death, pointing out every little thing.
And the general audience, that wants a good time.
I'm sort of in between. I know all about the franchise, and I love the aliens, but a little alien-death by the pred doesn't bother me in the slightest. Or the designs. Or the CG blood, acting, etc.
It looks good to me.
The highlight of this film for me, I think, will be the cinematography and fights.
