Better than 1 and 3, on par with 2. The dystopian universe is even more... I don't know...hopeless? Hundreds of years have passed and the whole thing is basically just some messed up experiment in the middle of nowhere. Everyone is long dead, Weyland-Yutani is gone. It honestly kind of resets the whole franchise.
Yeah it's got action movie feels, but so did Aliens. So that's a moot argument. The actors do a decent job with the screenplay which I think is one of Whedons better ones. This movie hits on a lot of the key notes and tones from the original trilogy. While bringing in some influence from the culture that made this franchise famous.
*SPOILERS BELOW*
The scene when the crew of the Betty enter the Big Military ship I thought to myself "These are the player characters if this was a game." This movie also did a good job on challenging my expectations. The first character from the Betty to die is "Coolguy Captain". Why? Because he wanted ANOTHER friggin gun even though he already had one in each hand. The dumb guys live and the slick ones all get chomped.
Granted, there are plenty of tropes and cliches which seem inescapable in a creature feature nowadays. That being said, It's still a fun horror movie night throwback. It was made right around the time CGI and practical effects were still used together to make something look GOOD and not too flashy *cough*Marvel*cough*. Movies used to be cinematic, now they just kind of feel like carnival rides.
