10 Easily Avoidable Deaths In Sci-Fi Movies
4. No Need To Jump In - Dr Susan McCallister (Deep Blue Sea)
You'd be wildly mistaken if you thought we'd give it a pass since test audiences demanded this via reshoot.
The demand made sense - kill off Dr Susan McCallister, given her role in creating the rampaging sharks. The production handled this by having Susan sacrifice herself - she cuts her hand and jumps in the water to distract the final shark and so prevent it from escaping. Now, this makes absolutely no sense.
The most prominent flaw here is that she could've easily achieved this without jumping in. If she wanted to use blood so badly, she could have tried spreading it on the water's surface. If she wanted to be more precise, she could've even wet something in her blood and thrown it in.
But the most egregious aspect of this decision is that she was a doctor who specialises in researching sharks. Undoubtedly, she must know several ways to distract a shark without resorting to something that unnecessarily risks her own life; it would've been part of her job.
It would've been much more believable if she had slipped and fallen in the water. But, astoundingly, this isn't even the stupidest heroic sacrifice by diving. That's for our next entry.
