Megalodon: The Frenzy (2023)

After surviving an attack by a megalodon that left the ship damaged and the captain dead, Lieutenant Commander Sharp must restore the USS King's engine to safety. Meanwhile, Dr. Clark's experiment goes awry, unleashing not just one but five megalodons into the sea. The film juggles multiple storylines, including a second warship and a potential tsunami. The movie features laughably poor special effects that make it a guilty pleasure. If you're in for some campy fun, this one's hard to beat.
