Glad movies like this still get made.

Rating: 9/10 (7 April 2018)

Even though it's very, very different Annihilation reminds me of "2001: A Space Odyssey". It's "true" sci-fi in the sense that it has you face something unknowable, something truly alien and not just an extraterrestrial variation of something you already know.
If you like movies like "A Space Oddyssey", "Solaris" or even something like "Moon (2009)" or "Sunshine (2007)" Annihilation is worth a try.
I understand why movies like this don't achieve great popularity or financial success but I'm happy they still get made.
