Deep Blue Sea 3. 2020.
This one carries on just after where the second film ends, there is no under the sea facility so this went in a different direction with marine biologist researching how climate change can effect the sea life including blood thirsty Bull Sharks. This is by no means better than the first but certainly better than two, my only gripes with this that the acting wasn't that spectacular and can be wooden and there is a bit too much talking but there is some good effects on the kills when they happen.
