Most reviews are namechecking Gravity and Alien when talking about this. I never managed to complete Gravity without nodding off so I can't fully compare but at least this is not as boring. The alien is nicely designed. And yeah, it's riffing on Alien but set in a contemporary UN-like space station. So it's missing all the cool future tech and design elements of Alien. It's quite gripping and the cast is solid. Made me squirm with a few scenes.
