I thought it was disappointing.
Bringing up all that deep and meaningful shit is a recipe for disaster, how can that ever pay off and be anything but a disappointment? It's a monster movie FFS, it's not like it's going to answer great philosophical questions like why we're here and the nature of religious faith, so why pose those questions so ham-fistedly and blatantly right from the start of a movie that, really, is all about scary chest bursting aliens?
It should have been left as subtext if brought in at all IMHO.
Ridley Scott seems to have lost the plot.
