Ah, the craze about this new Alien movie... We've had Prometheus : I thought people would have been vaccinated by now in what regards great, too great maybe, expectations... (What surprises me the most is the response to the concept arts before the announcement : I don't see anything transcendental there). Maybe Prometheus 2 will be better (I hope so).
But I'm not really enthusiastic about "Alien 5". I hope they will take the "good" road, and produce a very good movie, one to watch again with pleasure, a memorable one. Which means that there must be originality there. There must be flair. At least the experience of Prometheus - immense potential, but a mitigated result, in part because of "hollywoodian" reasons I guess - shows certain things to avoid. Between Prometheus and Interstellar, I choose Interstellar, easily, and I guess it's the kind of comment the studios could ponder about.
I hope that this next Alien movie will follow the steps of the first in what regards originality and awe. The collaboration with Giger and other talented artists made the first Alien magnificent visually and there was specifically a depth in Giger's work that nourished the imagination, the nightmare, the dread, etc. Prometheus 2 and this next Alien movie are the most adequate movies where we could find truly bizarre, awe and fear inducing elements of that kind. So I hope I won't be greatly disappointed in that area.
I don't know if the celebrated xeno has much cinematographic originality left to it. Variations on what we've already had, I can love it in a video game like Alien Isolation, which is excellent ; but it's not really what I expect in another movie, the fifth (in the AvP movies, they've used quite blankly the "Alien" recipe we all know - oh, eggs ; argh, chest-burster, etc. - and it's of course useless if there is nothing else on that point in the next Alien movie) or sixth in the Alien universe. So it will be a difficult aspect for the team working on the movie...
On the other hand, the cinematographic Alien universe remains extremely tiny. There are many ways of broadening the human aspect, show much more of the dystopian future society drafted in the movies, add depth to the quite simple elements of scenario and characterization of the Company, for example.
