Netflix Has A Must-Watch Sci-Fi Horror Movie That Nobody Talks About

Netflix has several great sci-fi movies on its platform. The only issue is that the streaming service has so much content that some awesome flicks get lost in the shuffle. Take Matthew and Kevin McManus' "The Block Island Sound," for example, which debuted to universal praise in 2020 before fading into the darkness, only to disappear from Netflix in early 2026.

"The Block Island Sound" tells the story of a mysterious force that's haunting fishermen off the coast of the titular island. It causes normal people to start acting erratically, and creatures from another planet may or may not be causing the terror. The less you know about "The Block Island Sound," the better. Expect unexpected deviations and leftfield turns that will keep you guessing throughout — but definitely watch it.

"The Block Island Sound" is one of the best alien invasion movies of the 21st century, but don't expect flying saucers and little green men throughout. "The Block Island Sound" operates more like a character-driven, paranoid thriller with elements of cosmic horror. Fans of Lovecraftian terror will have a blast with it, but what did critics have to say about the McManus' hidden gem on Netflix?

Not enough people have seen "The Block Island Sound." However, those who have typically hold it in high regard, as evidenced by its 90% fresh rating on Rotten Tomatoes. The film was praised for its subversive qualities and for showing restraint, as opposed to unleashing guts and gore. As Decider critic Johnny Loftus wrote, "[It's an] impressively-crafted horror indie with a boatload of suspense, a great sense of character, and the ability to frighten with neither ghostly nor bloody interference."

Josh Hurtado echoed this praise in a review for Screen Anarchy, noting that viewers will be rewarded if they accept the movie for what it's trying to accomplish. "If you're expecting a monster movie, you might be disappointed at the lack of blood and guts, but if you'll open your mind, 'The Block Island Sound' just might scare the hell out of you."

There are valid reasons for canceling one's Netflix account, but "The Block Island Sound" returning could be a strong case for keeping it. If you are in the mood for a movie that will get under your skin, look no further than this terrifying sci-fi treat.
