So, I'm pretty psyched about Ridley Scott's Prometheus. It's a space opera following the crew of the starship Prometheus. And unless Scott has lost it, it'll be a thoroughly enjoyable sci-fi adventure.
I have a thing with sequels: I like continuity. Re-casting an actor takes me out of it. Sometimes a "movie reboot" is the solution to whatever ailed the old series; other times it's a death-knell to a flawed diamond. Turns out there's a third option: the pseudo-reboot.
JJ. Abrams Star Trek (2009) was created in such a way that if you were new to Star Trek, you could disregard 40 years of baggage. On the other hand, if you were a trekkie (( Or trekker, I don't care about the difference. )), the movie gave you a straw to grasp at which would acknowledge those 40 years of continuity. Star Trek did the impossible — provide an entry for new movie-goers yet satisfy (the majority) of the trekkies, all the while actually being a good movie! I don't even need to explain to you what exactly Star Trek did to respect the old continuity, that's the point. If you didn't pick up on it, it's because you don't need to worry about it.
Now watch this:
That's continuity. If you want it to be. Did you get it? You might prefer not to read on.
Turns out Prometheus is a pseudo-reboot of Alien. Peter Weyland is the co-founder of the Weyland-Yutani corporation, the evil conglomerate and eternal nemesis of Ripley. Which means, if you're an Alien fan, you can consider Prometheus a successor to Alien. If you like, also Aliens. Perhaps even Alien 3, but I would expect most of you to disregard Alien Resurrection (whose only good part was the whiskey cubes). On the flipside, if you don't care about Alien, you're unlikely to watch the above viral video. You're probably unlikely to even care. But there's a chance you might go watch Prometheus anyway because every effort has been made to convince you it's its own thing. The continuity is optional, and I like that.
