Seeing that the one writer isn't involved and that Prometheus had a fair amount going for it (namely visuals, although I'd say that's more about the cinematography than the visual design which wasn't particularly noteworthy, just like a more organic version of the Alien design), I'll see it at some point. But I'm not obsessive about the franchise or Scott's work (I like some of his stuff but I don't really find any of it the seemingly transcendent experience that some people apparently do). If the feedback is good I'll probably have more interest in watching it, if its mixed like Prometheus was then I'll probably just watch it whenever it ends up on Netflix.
I'm much more interested in Alien 5, although there's a distinct possibility that it might not be good, especially if its actually trying to make the overall story post Aliens work.
It wasn't supposed to be named that at first...originally he called it Paradise or Paradise Lost. I'm guessing the studio pushed him to make it more like Alien so they changed the name to attract more people.
I personally think the trailer looks pretty interesting...but then I am a fanboy of the series.
Prometheus I think was originally a full prequel to Alien but then Scott wanted to change it supposedly so he wouldn't have to make it feel like an Alien movie.
I think there's some truth to that ("cinematic universe"), but Scott made Prometheus an Alien movie he just didn't call it one (because there are differences, but its set in the same universe, has blatant similarities in design and other aspects). Honestly I think it was just some nonsense where Scott wanted to either art it up (Prometheus! Its an origin story!), and felt that the Alien franchise was tarnished and would hurt its chances (as people would come in expecting a typical Alien movie). I think now he can drop all pretense and maybe he can win over the people who hated Prometheus.
