You are right about everything from Alien 3 through Covenant. However! Romulus was pretty okay. It has some questionable plot decisions, and it's kind of soft continuity compatible with the two Prometheus-era movies. But it does work as an action-horror in the shared universe of the original films. Alien: Earth was also pretty good, it explores the setting without breaking it too badly, and it's fun with dangerous aliens that aren't THE Alien. There are some plot points that require very smart characters to be holding the idiot ball.
