The Force was a much cleaner concept in ANH.
Based on what Kenobi has to say, the Force is really no more than a transcendant meta-reality underlying our "apparent" reality in the same way that Plato's Forms lie under the "world of appearance".
Some individuals are able to directly access this meta-reality, and that allows them to do fun things like fight with a lightsaber while wearing a blast helmet or make amazing shots without a fire control computer or make objects fly through the air.
In this view of the Force, the "Dark Side" wouldn't be a distinct element of the Force at all, but merely a human way of interacting with the Force - by using it to destroy. The "Dark Side" is powerful and tempting because human beings are destructive creatures, so using the force in this way both appeals to us irresistibly and is easier for us than more positive uses. This easiness makes the "Dark Side" appear to be a more powerful mode of employing the Force.
The prequels and the EU really screwed up a pretty simple concept.
