Quite interesting sci-fi horror about killer fungi living deep below the surface. I really wanted to like it but there's so much wasted potential in here and it’s way too long for what it is. The production is top-notch. The visual effects and set design are the best part of this film. Those gnarly gross effects and the monster design look fantastic. It starts out really promising but then it kinda loses its steam in the middle. It could've been a simple but great monster film if it wasn't trying too hard to be more than that. It's just hard to keep my interest. It falls apart towards the end with lots of issues. The dialogue is terrible, there are some unnecessary slow-mo with sad music in the background, and lots of confusing characters' action. The characters fail to show any significant emotion, especially when they're in danger. The relationship between Anna and that soldier feels forced and make zero sense to the story.
