If it's crap ... We'll tell you
I'd say everything after the caesarean scene could of been done a hell of a lot better. And the very last scene in the movie just made me think of the ending to AVP, left me with the same feeling also.
The films story stops right at the Engineer. After that, it's one big mess of a giant face hug. They could have left that out, and stuck with the to be continued ending. That would at least explain the chestbusted Space Jocky in the first Alien film. If we don't get any answers, all this is. Is a good Sci Fi flick with a dumbed down ending, just to get Joe Schmo's to like it. I almost gave it a high matinee, but as an Alien fan. I had fun piecing together the who what and why's.
This should have been in the movie. I had seen it before i went, and i think it and the commercial for TED adds to the film. Most folks don't even know they exist. ...
