Recently watched Romulus, like two weeks ago. Personally, I loved it, thought it was great.
I had also tried to watch Aliens (plural, the sequel) holy shit it is so trash. And yet it was considered a hall mark of the time. It takes over an hour for the aliens to show up, and in the meantime you have to deal with dumbfuck marines who are supposed to be the best of the best but are undisciplined fuckwits that make the term "crayon eater" sound like a compliment. Then they do show up, and the marines are just the biggest idiots. I cannot stress enough just how trash this supposed classic is. Also, probably a hot take, but Weaver is just a product of her time and heavily overrated.
I also watched AvP and AvP: Requiem, and both of those movies were a much more fun watch, though Requiem really does drop the ball with way too many dark shots, its a common complaint about the movie for a reason. There's a lot of complaints about lack of character depth too, but my own response is who the hell cares when most are just going to wind up dead. I'm definitely not watching Alien or Predator movies to be enamored with the basic humans. And they're all better than the trash Marines of Aliens.
