Corrected entry: Towards the end of the film when Carter is being dragged along by the shark, the shark rams into a wire fence. You can see that half of Carter is dragged through the hole in the fence. When you see the underwater shot of the shark exploding, Carter is to the left of the whole and is within the compound. When Preach calls out to him, he is outside the compund. How did he move so fast? (01:35:40)
Corrected entry: In the scene where the head scientist takes her wetsuit off to electrocute the shark, her wetsuit is soaking wet so it would make no difference if it was made of rubber or not, she should have been shocked as well.
Corrected entry: Mako sharks can't get that long.
Corrected entry: For the entire wet lab scene, the Mako shark is half-submerged in the pool. We are to assume that sharks only need to be in water to survive. However, sharks must also keep swimming in order to get oxygen-rich water into their gills. Without this, they would drown or suffocate. Certain species, such as the Nurse shark or the Australian Wobbegong, have adapted to remain motionless on the ocean floor for hours at a time. But an oceanic species like the Mako would have died in the wet lab's conditions.
Corrected entry: Sharks are attracted to the smell of blood not the sight of it or something that looks like it. So in the opening scene when the wine is knocked over into the water it shouldn't be a big deal.
Corrected entry: When Preach gets into the oven the water level is at the middle of the window. The level would be the same inside, it's not air tight.
Corrected entry: Those big sharks can tow a helicopter and yet in the opening scene, when Carter catches this shark, the shark is not able to tow the boat, which the harpoon is towed to.
Corrected entry: Am I the only one bothered by Preacher getting bitten so badly he nearly passes out from the broken leg, yet when he is either shooting at the shark and Carter, or setting the wires, he stands easily on his injured leg? At first the leg seems to inhibit him, but it must magically heal as the movie continues. (01:28:55 - 01:34:05)
Corrected entry: How did the sharks know that they could "sink" Aquatica? It was already underwater. Were they genetically enhanced and provided with blueprints on how to do this? The whole concept is flawed. Despite having enhanced intelligence, they would still have to learn that CCTV cameras transmit images to the cast. They could never know that wounding someone would bring a helicopter they could use to sink the structure. The whole concept of the film is based on the, frankly, wrong assumption that being more intelligent makes a creature automatically 'know' more stuff. Well it doesn't. It would just make them more able to learn and understand. So who taught them?
Corrected entry: Sharks don't make any sounds.
Corrected entry: At one point in a shaft L.L. Cool J's character throws down a rope to save a few of the characters from the fast rising water. The shot shows them pull back the rope and shut the door. A few scenes later, the rope is hanging down the shaft again. (01:08:25 - 01:12:05)
Corrected entry: Near the end of the movie when the three are preparing to exit the sinking building and float to the surface the comment is made that putting the life jackets on will cause them to float to the surface too quickly and their lungs would pop. When you watch them swim to the top, they actually swim faster than the jackets/fire extinguishers go. (01:24:30 - 01:26:50)
Corrected entry: In the beginning when the blonde-haired ex convict was in the tunnel surveying the sharks, the sharks co-ordinated an attack in which they both hit the tunnel in the same second. How could they have done this? Becoming smarter does not give them the ability to communicate.
Corrected entry: The sharks cut the electricity for the lights when they were trying to catch Carter. However, when the helicopter comes Brenda is using a spotlight.
Corrected entry: If these sharks are strong enough to open metal watertight doors, how come they couldn't break through the fencing without sinking the place.
Corrected entry: Several times, the sharks swim backwards to move down a different hallway or change direction. This is an impossible feat for sharks, regardless of their intelligence.
Corrected entry: Considering the huge size of the glass window in the facility and the fact that it is so far undersea, it must surely be several inches thick and therefore able to withstand an immense amount of pressure. Yet it breaks ridiculously easily when the shark rams the lightweight gurney into it from a considerable distance. If it was that easy to break, how come the sharks never tried it before themselves, especially as later in the movie they can knock out heavy steel doors without any effort at all?"
