Makes the Meg seem like a nature documentary
Realism is very far down on their priority list apparently. Forget the physics defying action sequences which is common in movies these days, but how about things like amphibious creatures that have been living on the bottom of the ocean for tens of millions of years and yet they pop back up on land and walk around like they do it every day and haven't evolved one bit in the much different ecosystem that they've been trapped in for generation after generation. (And they can either hold their breath for a long time, or breath both air and water).
5/10 at best.
