I really liked the newest 3 alien movies for what they were. You aren't getting a bunch of 80's/90's horror action but you are getting some pretty disturbing kills and a unique sense of dread, a legit incredible actor, etc. The first couple kills that start in the medical lab in Covenant was all time sci fi horror material.
And then Romulus those first scenes/shots of the mining planet they were on, you can't get better sci-fi cinematography than that. Bonus points for how creepy it was to revive a deceased actor with AI. Bonus bonus points for again nailing the casting and getting Cailee Spaeny who is girl-next-door fucking hot and great in everything she's in.
They are goofy at times trying to introduce the Protoss looking aliens and Prometheus was the worst of the 3 which is why people probably gave up on the series, but they are great horror films and pretty unique.
I see they're making a movie adaptation of Alien Isolation which is almost guaranteed to get back to the 80's/90's style of the first movies.
