Alien Romulus is a fresh viewpoint of this wonderful franchise while preserving the previous releases. My only two complaints would be regarding some physics technical slips i.e. any objects that are brought together by gravity do not just go apart without an external force once the gravity has disappeared, the second one, liquid in space tends to become a bubble, molecules tend to bind together, whereas alien blood was kind of ...dispersing ...you will see what I mean, the second complaint would be about the decision to bring back the original Alien movie android...it looked like quite bad CGI.
The positive would be on the rest of the CGI, storyline and integration between the first and second Alien releases while filling the blanks of the franchise overall.
