Alien 3 did the beautiful birth thing next to dark but hautingly beautiful score, i still get chills from this:
Covenant brth scene doesn't belong in a proper Alien film. The music on it's own is not bad, it's pretty but it completely lacks the dark undertones that an Alien film requires. It probably would fit nicely to some romantic movie. It's still musically one of the strongest moments (that wasn't reused Goldsmith) in the soundtrack. Some of the Covenant scenes are just bad taste, e.g the K-Drama esque sappy piano music with Daniels. WTF were they thinking.
Tbf the shocking chestbuster wouldn't have been effective either when there was pretty gory b2b backburster/throatburser earlier and the build up for the chestburst was horrible and the result was just laughable in the end.
