The Descent 3 sci-fi?

Rating: 7/10 (1 April 2018)

A meteor crashed into a lighthouse. Then a girl named Lena is debriefed in some facility. The guy doing the debriefing is wearing some hazmat suit. Previously, she was a biology professor mourning her husband who went missing after some military operation a year ago. The day she decides to paint the bedroom a different color he shows up but can't give any explanation and doesn't say much at all. When he starts bleeding he's taken in an ambulance but man in black show up. Next thing we know Lena is in some other facility where she's told what's going on.
After the meteor crashed some colorful gooey transparent wall appeared which is expanding over time. They call it "the shimmer." Whatever goes through it doesn't come back--except for Lena's husband but he's in a coma now. Running the show is some psychologist for some reason. She's recruiting people for yet another mission through the shimmer. She assembles an all-female cast (in what universe is that cool?), Lena among them of course, she volunteers because she thinks she owes it to her husband. In any case, off they go. On the other side it looks like a normal jungle. Except that eventually they see odd colorful vegetation and mold. Lena concludes it's some mutation. The find a house and are attacked by a crocodile. When they kill it they realize it's also a mutant. Then they are attacked by some bear-like creature. They find the place where the previous group was station. They left a tape where Lena's husband opens up another guy's abdomen to reveal some slithering inside--perhaps the guy's intestines, perhaps something else.
Our team notices that something goes on with them as well. One girl's fingerprints move; Lena examines her blood and the cells are mutating. And of course they start going bonkers attacking each other. They find abdomen guy exploded on a wall covered with the colorful mold. Farther away they find plants in the shape of humans. One of the girls comes to a realization. Just as the light reflects, so does everything, including DNA. That's why all the mutations. She does something extraordinary. Instead of wanting to face or fight whatever IT is, she gives up.
The plan is to go to the lighthouse, but by now the number of team members is dwindling. Lena of course makes it to the lighthouse, finds another videotape involving her husband and a surprise. She goes through the hole where the meteor landed. Are here the filmmakers didn't shy away from he sci-fi but give us something of an explanation. I won't reveal what goes on but it's pretty fascinating. At the ending there's somewhat of an expected surprise but it's an unsatisfying one because it goes against what we saw earlier.
Annihilation is a slower, longer, but satisfying sci-fi movie. They probably could have done more with the mutation aspect in the jungle but fortunately keep the human drama and fighting to a minimum. The final act is intriguing. We even learn some interesting bits of science.
