When it comes to creating a villain, writers have two options: They can either pull a Macbeth (or for the Shakespeare-averse among us, a House of Cards) and lay out the villain's intentions from the start, or they can keep the audience in the dark. It's an understatement to say that Lost's writers leaned towards the latter method.
Ben Linus was the perfect antagonist for a show that reveled in its mysteries and was content to keep a number of them unsolved. One fan (@manostorgo) complained of Linus, "The end justified the means. But we keep seeing the means and not the goal." Whether or not you find that kind of storytelling pleasurable, you can't deny that the enigmatic Linus was a villain precision-cut for a show that answers each question with a new question.
