After Deep Blue Sea taught us that even the smartest shark flick can be incredibly dumb, Deep Blue Sea 2 came... decades later, to show us that no, not all good things come to those who wait. That did open the door for even more sequels though, which we (blog post) have with 2020's Deep Blue Sea 3. A tale of... sharks. They're kinda smart, and they eat people. Why do I feel like we've seen this all (blog post) before?
