The idea definitely has potential, now it depends on how good the script, acting and effects are. Sigourney Weaver ended up as a inevitable inclusion in the previous films so hopefully they can wean themselves off her.
TBH none of the Alien films was a total disaster, unlike some sequels, but some were definitely better than others. I still think the original was the best so far.
This wont be an Alien movie, you need to understand. They may come out of this movie in the sense this is the same universe and you may see one or start of one at the end of the movie BUT...
It is more about that alien ship then anything else in terms of its link, at least where it came from, about the race etc.
