I could say this website has potentially ruined my movie-going experience as far as the alien franchise, but I suppose it's just the way the world is going. Knowing the entire movie before it comes out, showing the entire movie in the trailer, etc. And that's fine, those are things the viewer can control. Coming to a beloved AvP site, and seeing spoilers posted on the front page? I guess it's my choice not to come here also.
I'd ask for some consideration on your part, but I'm guessing an overwhelming amount of fans that come here probably want to know it all within seconds of entering a website, which is fun too because they can discuss it. But I don't think you need to blatantly whip it all out there. They've already come to the site.
You already have their attention.
