At the end of the day, Alien 3 is still a sci-fi/horror film. There's a certain amount of the audience that are going to see the egg and just go, "Yep, that's an alien alright. Yep, oh better watch out there Sigourney". And then they'll just watch the movie with no more thought given to it.
I honestly don't care about the hugger anymore. Was it executed poorly? Yes I think so. But there's really nothing that can be done about it at this point. I just enjoy the movie for what it is.
