I've seen it.
And its not good.
Biggest movie disappointment of the year. Trailers had me thinking this would be a classic. But almost nothing in the second half works. Its just a mess. The creatures weren't scary and felt like something out of the Star Wars prequels. And the last shot of the film is an embarrassment (you'll know when u see it). I definitely don't consider this a part of the alien canon.
I like the concept of the film and theres a lot of great ideas in it but it just falls apart very early. Fassbender and Idris Elba are great. And there is a scene where they inspect a space jockeys head at the lab that is awesome and felt like something out of a Paul Verhoeven movie. And the c-section scene is intense and scary. But overall this is just a mess
