I mean, conceptually, sure that's a very scary thing that happens within the movie. I don't think that's the scariest thing about the movie though. Nor do I think it's the scariest thing the creators of ALIEN came up with for that movie.
It may just be me, but the original comment just comes off as smug rather than trying to honestly add observations.
I mean for 1979? A lot of males probably DID think it was horrific. I don’t think males were allowed in the delivery room UNTIL the 70s, and choosing to actually exercise the option became more common in the late 90s/2000s.
I think your comment really dismisses the fact that Alien feels like a modern movie in a lot of ways BECAUSE of these types of deliberate choices made during the writing and filming. The movie is over 40 years old.
