You can say a lot of negative things about Res. It's schlocky, it's campy, it's derivative, it's predictable, it's by-the-numbers, it's contrived, it's action-y, it's not horror, etc. Fine. That being said, I can describe Romulus in one word: shameless. For all its faults, I never thought Resurrection was outright shameless (maybe the panning shot of Kim Flowers' butt, however I can abide that).
In this case we're comparing a mediocre movie (Res) to a movie that borders on being outright offensive if you have respect for the series up to that point, in its ruining Ripley's triumph at the end of Alien, in its f**king up of the timeline, and its choice to substitute ripping off the original films instead of adding new content. And it doesn't really matter if some of the setpieces or aesthetic or effects or visuals are "better" in the latter when the movie as a whole is an eye-rollfest of easily avoided mistakes.
