The only way it can be made good is if they talk and base it around the mothership from the 1st film and who were the other aliens transporting them! But they wont it will be another hollywood quick $$$$$ type of film.
Edited to add a great quote from my fave Alien film:
All right, sweethearts, what are you waiting for? Breakfast in bed? Another glorious day in the Corps! A day in the Marine Corps is like a day on the farm. Every meal's a banquet! Every paycheck a fortune! Every formation a parade! I LOVE the Corps!
Everybody has secrets, life would be boring without secrets, don't you think...?
