Imagining An Underwater Jurassic Park

   It's pretty much confirmed that Jurassic Park 4 will take place on land, but an idea that has been kicked around amongst fans recently is that of an underwater Jurassic Park. I, too, have looked at the prospect of an underwater Jurassic Park. I have come to the conclusion that the film would either be a critically acclaimed masterpiece, or it would be a critical flop that taints the whole series.

   There would be an opportunity to present the fans with a number of new animals, like the Livyatan, Basilosaurus, Liopleurodon, Megalodon, Ichthyosaurus and Plesiosaurus.

   While it could potentially change the critics' opinions on the series being stale, there is an even greater chance that it would be perceived as a drastic unneeded and unwanted change. Sure, a 50 foot Megalodon attacking a boat would be cool, but it just wouldn't make sense for a number of reasons.
 

    First, you must consider that there has to be a way to get DNA. While the idea of frozen aquatic parasites has been used in Jurassic Park: Builder, it would be criticized if used in the film. A lot.
   Second, couldn't the people just leave the water? Seriously. Get out of the water. Simple.
   Third, what would they be doing in the water in the first place? Searching for missing people, perhaps?
   Furthermore, what would keep the creatures in place? Wouldn't they just swim away? If they were contained, then the only way you could get killed would be swimming in their habitats.
   Lastly, you would have no chance of surviving an attack. If a T-Rex partially crushes your car, you can escape. However, if you're underwater and a Megalodon bites your submarine, you're dead. Dead from the neck up, dead from the neck down. If the pressure didn't crush you, the Megalodon would eat you or you would drown.

    While it would be cool to see giant pliosaurs and stuff, it just wouldn't make sense. If people want to see a giant shark on a rampage, they should watch Jaws. The majority of people want to see dinosaurs in Jurassic Park, not fish.
