The positives were easily the production value, aesthetics and attention to detail. It mostly looks and sounds real nice. The birth scene at the end was done really well, as was the xenomorph killing the anti-android guy and climbing out that wall vagina lol. It had some cool visuals that I'll remember even as memory of the mediocre script fades. The pacing was good too.
But the negatives continue to mount up the more I stew on the experience.
I'm noticing more and more that, in modern sci-fi, the world-building takes precedence over creating interesting characters. I agree with
@Vegard Pompey that the first half did well at establishing a kind of gritty, grimy hopeless mining planet hellscape, but who really cares if the characters in that world suck? Say what you want about the Alien franchise post-1979, but even the weakest of the original four films had cool, interesting, memorable characters (Charles S. Dutton, Ron Perlman, Brad Dourif, Dominique Pinon!). Romulus has the most boring, forgettable cast ever. Yes even the lead actress. Pretty bad when your most memorable character is an AI abomination of dead actor Ian Holm.
They couldn't have worked up an animatronic Ian Holm puppet for the role like they did with Lance Henriksen in Alien 3? I thought these losers were supposed to be doing an old school homage to the franchise?
Speaking of, this movie made xenomorphs, once again, into mindless cannon fodder. Like
@rms said, we were lead to believe this was supposed to be a return to HORROR Alien, and yet it winds up being just a lamer Aliens that didn't have the balls to at least be action-packed. They jammed all the action into the final act with the aim-assist rifle...
They even repeated what Aliens did by making the space station into a hive, but we didn't even explore much of it due to the imminent crash subplot.
Aliens made sense because the characters were all heavily equipped soldiers, why did we need a space station filled with xenomorphs, facehuggers and a 7'7" xeno-man to terrify 5 young adult dipshits and a cuck-droid? Mind-boggling decision. It should've just been 2 rogue xenomorphs hunting them down, back to basics etc.
Don't even get me started on how PISSWEAK the final fight with the giant human xenomorph looked, as the lead is dangling out in space as the shit is colliding with an asteroid belt. It was a greenscreen nightmare with a side dish of CGI human xenomorph face disintegrating slop.
To me Romulus is like the Rogue One of the Alien franchise with how it takes place between the first and second original movies, relies on nostalgia, but isn't a caricature of itself like most nostalgic projects. A fairly interesting but ultimately rehashed step in the right direction, however so slight. I'll still take it over Prometheus and Covenant anyday.
