This is absolutely 110% very slow paced and unnecessary scenes and stories. Most of the time when Alien appeared was shot in the dark, easy for the director to show an Alien. Every time someone is crying, you can see excessive Glycerin in those actors eyes makes it look everything is so Fake.
The story writing is just so cheap, they are filling time e.g a husband is having an extra marital affair. What it got to do with Alien invasion. The director and story writer need to find a new job of filling grocery somewhere.
