Two Bullshit Sci Fi Stock Devices

Sci Fi is often the most inventive and interesting genre out there. That doesn't mean it doesn't have its fair share of lazy writing, though. What do the lazy writers do? They fall back on these:



1) Evil organisations that execute their own employees

Now, I'm not saying that no company has ever killed an employee of theirs but this device is never about realism. This device is used by extremely lazy writers as a way of saying: Look! Look! This company is evil! They're killing their employees! Bastards!

The thing is, it's usually totally pointless. It's always done when an employee has "served their purpose" or "seen something they shouldn't have". If an employee has served their purpose, get them to do something else. It's no wonder a company has to keep hiring assassins if they bump them off after every successful job. And if they've seen something they shouldn't have... good for them. These are Sci Fi films, remember? It's not as if they can ever go to the press or the police in these films...

Worst Offenders:
Prototype Scientists try to save a mans life, he wakes up and escapes. Solders ask scientists a few questions and then kill them. Those scientists probably had some useful information, you know. Now you'll have to spend days going through their research and working out where they were in their projects.
Cube 2 A covert operative goes through hell to retrieve some data from the ultimate hiding place - another reality. How is she thanked? With a bullet to the back of her head. She is probably the most talented individual in your company, guys. At least try her out at marketing or something first...


Are there any examples of this actually working?
Not in Sci Fi, as far as I know... Leverage had an episode called The Mile High Job which played with this concept very nicely though.



2) Ultimate Stop Anything Force Fields

What happens when a force need to invade a planet? They need to stop the populace defending themselves. Clever shows like Battlestar Galactica have the enemy infiltrate the humans for years in advance, learning about them and planning precisely where and when to strike.

Lazy shows have the enemies invent a force field that will stop any weapon in the world, including nuclear bombs.

Now, I can cope with the idea of a force field but what's important to remember is that for every action, there is an equal and opposite reaction. If a nuclear bomb explodes on your fancy alien hull I don't care if you've got a fancy force field, you're still being sent flying a few miles in the opposite direction.

Worst Offenders:
The War Of The Worlds Remakes, Independence Day etc. etc. etc.: This is especially bad in War Of The Worlds. They hit the aliens with missiles, rockets, bombs... the damn things don't even flinch. That's not how physics works, guys.

Are there any examples of this actually working?

Oddly, yes. The Christopher Eccleston series of Doctor Who gave their ultimate death machines, the Daleks, a stop anything force field. It's different for two reasons, though. Firstly, bullets fired at this force field are not stopped in their tracks, they are slowly absorbed... the implication being the daleks are using the power and momentum of these bullets to power their own systems. Secondly, if you and several buddies concentrate your fire on one small are, you can break through the force field and do some real damage.

Granted, in series 2, 3 and 4 of the same show this rather clever sci fi device get's unceremoniously stomped on by Russel T Davies, one of the all time great Lazy Writers but it was good whilst it lasted.
