Saw it today. I wanted to like it. I really did. But I just didn't. I liked the beginning, pretty much everything until the first penis alien opened up to reveal its vagina mouth. Unfortunately it never recovered. From alien c-sections which barely phases the mother who doesn't tell anyone about it, to "shocking" reveals that I could have called from the first 10 minutes. Vagueness abounds, and even after reading theories (especially this one that pretty much says the Xenomorphs were made because we killed Jesus) I'm still not sure what the movie was trying to say. It certainly took a long time going nowhere.
And that was not a Xenomorph at the end, not phallic enough.*
