That c-section was simultaneously the best and worst part of the movie for me. The scene itself was great. Thematically and artistically, it was on-point. It felt like exactly the kind of scene that belongs in an Alien movie.
What I hated is how the rest of the cast failed to react after it was done. They had been trying to capture her, she gets away, gets it cut out of her, and then everyone seems to forget or forgive just because that old guy was coming out of cryo-sleep. They should not have been so easily distracted.
