Geez. You're all acting like a time-travelling, Predator killing, back-from-the-dead Ripley is a bad idea!!
It's kinda the karma a lot of this fan base deserves from where Im sitting. All the people who say they want a new direction with new characters and adult themes, were delivered exactly those things and hated it for not being more like what already was.
Now, Im not saying there arent some of the fan base out there who see the prequels for what they are, on their own terms, with their own flaws, but ... HOW SOON WE FORGET!
For Predator fans, no karma deserved this. At the time we had three films to speak of, and while some fans may not be fond of "Predator 2" and/or "Predators", there has never been a mass fan outrage over them that was going around
, to deserve what came around
: An 11 foot Predator, an iron man suit with dreads, tons of comedy, a friendly Pred-Dog, and a child suffering from autism equating to a true warrior.
I guess you could solely be looking at the time-travelling, Predator killing, back-from-the-dead Ripley scene and suggesting that is karma for Alien fans frustrated with the prequels, but it didn't even make it in the movie. So I don't see any karma in play at all, if you buy into that sort of thing.
