Good suspense and cast. Kristen has definitely improved as an actress.

I enjoyed the movie, it kept me on the edge of my seat. My only complaint was that it wasn't super original. It felt like watching Alien, just under water.

Well designed horror structure. Good, well-earned jump scares. Engrossing story, and it can feel either prophetic or cautionary about corporate greed,

The movie was thrilling. However, some parts were hard to follow.
