She absolutely had a reason to go looking. Nobody's questioning that.
But that she found an Alien, had this massive adventure, it resulted in the destruction of a space station, And then all of this gets covered up and all that gets back to Ripley is "Yeah nah she got married, died of cancer, not much to it?"
That's my problem. It's that bullshit "tHeRe wAs a coVerUp" handwaving to shoehorn whatever ridiculous scenario for no good reason.
