Someone else already picked my favorite shark movie, so I chose a more recent one.
My choice: Ice Sharks (2016) A classic B-movie sci-fi horror in which an Arctic research station is attacked by a unique species of shark that can swim and hunt beneath the ice. The scientists trapped at the research station must fight back as the facility begins to sink. It’s a very exciting movie.
I recommend it to everyone, because Mindless entertainment: The story doesn’t require any serious thought. It’s a perfect choice after a tiring day if you just want to occupy your mind with an outlandish and absurd premise (killer sharks swimming through and wading across ice).
