Annihilation starts off slow as do many sci-fi films that build up to a main event or events. Personally, I like a sci-fi film that jumps right into the action like Mad Max or Pitch Black. However, Annihilation is classified (at least on IMDB) as a horror drama rather than science fiction so maybe asking for more action is fruitless. Let’s just call this a psychological thriller which it really is, recalling films such as Jacob’s Ladder, Requiem for a Dream, and Inception. Read the full 4k Blu-ray review of Annihilation.
