    📽️ Tonight we watched SEA FEVER on #Shudder & I was thrilled to find that it was an engrossing, terrific #film. If you like your #Horror briny w/ a tinge of the cosmic, check it out. It'd make a good double "creature feature" w/ ISOLATION (2007) (another fantastic little gem- it's on #Tubi).

    While I am easily pleased with this type of film, Sea Fever is well made with a fantastic lead character/performance. If you like space/sea Sci-fi horror, I'd definitely recommend it. 📽️ My ★★★½ review of Sea Fever on Letterboxd boxd.it/aufo1d 📽️ #Filmsky

    Hit #100HorrorMoviesin92Days success on attempt 78, Sea Fever (2019). Folks will call this The Thing on a boat with a hot redhead* lead and they’ll be right. Also with Connie Nielsen. Claustrophobic without being suffocating. Very good, may have to revisit *probably unnatural, but it works on her

    I just watched a great, little claustrophobic Irish sci-fi horror movie called "Sea Fever" (2020) on AMC+. It's like "Alien" but on a fishing trawler. A mysterious parasite has gotten aboard by infecting the freshwater supply. 8/10

    Some spooky season movie reviews: SEA FEVER (2019), an Irish SF horror flick about a fishing boat stumbling into the path of an undiscovered marine monster and its parasitic young. Ends with a bit of a shrug but up until then it's effectively scary ALIEN riff without being TOO derivative.

    This is a great example of what can be achieved by setting a movie in a small, claustrophobic location and arming a more than capable cast with a decent script. I'm now in the mood for more under-the-radar seafaring horror. Recommendations please? SEA FEVER gets a very solid 7 out of 10.

    "Sea Fever" is a fine film, an odd cross of The Thing and The Bay (but without the impersonating lifeforms), with a somber ending. Not a bad film, a solid horror if you have Shudder or easy access. The sea is inherently terrifying after all

    Last night's 2nd movie was Sea Fever. Was on my list for a while. More character driven than pure horror. Takes just a bit too long to get going. But it has a terrifying premise, a hint of Lovecraftian sea horror, & an unexpected gross out jump scare that was gnarly. Enjoyable, but not scary.

    Obviously done on a shoestring budget, this is actually quite an interesting little sci-fi/horror mystery. It all centres around the crew of a stranded trawler who come to realise that there is a malevolent beastie that has found it's way into their water supply after their boat strayed into a restricted area. Luckily "Siobhán" (Hermione Corfield) has some scientific skills and plans a way to stop this lethal parasite from killing (rather messily) not just the people on the boat, but anyone…

    I thoroughly enjoyed this. It's the first thing I've watched recently that didn't feel like they could (and should) shave an hour off of it. A nice, light watch that had a unique concept and a likable cast. I agree with others that the eye popping scene was about as intense as it got, with everyone else dying in fairly lackluster ways. I'm not normally one to say up the gore, but a bit more would have made the second half feel more intense and urgent. I also couldn't help but find it amusingly…

    It has a promising plot but somehow it lacked substance, especially towards the end of the film. Somehow I was expecting a conclusion to the entire “monster” situation, but then it was left unattended. Overall, I enjoyed watching the film though. Would I watch it again? No. Would I make my friends watch it? Possibly.
