The more I sit with Annihilation the more the ending bugs me. Basically everything after she enters the "nest". Not enough to ruin the rest of the movie but the rest of the movie deserved something better than what it got.
It wasn't even like a gymnast pulled off a really nice routine and then stumbled at the landing, it's like they pulled it off then just stopped, flipped off the judges then walked off the mat.
Curious if the dude just couldn't come up with a way to end it, or if it was studio interference attempting to make it something more traditional and less ambiguous than it could have been.
