"Annihilation" is being called a sci-fi masterpiece you'll still be processing long after the credits roll.

Critics got a sneak peek before the film's release on February 23, and they were deeply impressed.

This shouldn't be a surprise to anyone familiar with author Jeff VanderMeer's Southern Reach Trilogy + Alex Garland's history as a brilliant sci-fi writer ("28 Days Later," "Sunshine") and writer/director ("Ex Machina").

Garland both directed and wrote the screenplay for "Annihilation," which stars Natalie Portman, Jennifer Jason Leigh, Gina Rodriguez, Tessa Thompson, and Oscar Isaac.

Without delving into the movie's plot at all, just check out some of the first reactions:

Well, you can't ask for much more than that. If you're curious about the source material, consider checking out VanderMeer's 2014 novel series, starting with "Annihilation" and continuing with "Authority" and "Acceptance." The film version of "Annihilation" opens in theaters Friday, February 23.
