I am surprised by my reaction to this, Alien 5 was something I looked forward to when I first heard of it and was excited because I liked Blomkamp's District 9 movie.
But the moment Ripley was being brought back, it just began to kill my excitement as it feels like a rehash of Aliens, and I mean literally, Ripley + Hicks + Colonial Marines... I'd much prefer they just used Colonial Marines with some new faces to introduce us to.
But hey, we're technically getting an "Alien" film, it's being done by Ridley. So you might as well call it "Alien 5" due to its title. Some were saying Prometheus may be retitled as "Alien: Prometheus" to bridge it closer to the Alien brand.
