I do find Lost to be great entertainment. But there's one aspect to the story arc that I find incredibly irritating, which is explained better than I could explain it by Peter Suderman:

This kind of thing plagued The X-Files too. I like Lost a great deal, but the length of time they go without resolving key mysteries is somewhat irritating. I strongly prefer storytelling in which the major mysteries don't go unresolved for more than a season or two. To stretch things out longer than that seems like kind of a cheat to the audience. Of course, once a mystery is resolved, you can introduce new mysteries, but there's no good reason why some of the most basic questions from seasons 1 and 2 (like **what is the island all about?**) are still unanswered as of now.Here’s the problem with Lost. It asks “why” but answers “what” and “how.”
Spoiler alert!
In tonight’s episode, for example, the last before a month-long break, we see Michael, in flashback, go through the steps that led him to pose aboard the boat as a deckhand.
He’s told of the fake plane, and is informed that the boat’s crew have been ordered to kill everyone on the island. But when he’s given this information, he doesn’t ask the obvious question: Why? Why would anyone want to kill the people on the island? Why would anyone think the island, or its inhabitants, so important as to stage such a ridiculously complex hoax? It answers the simple why — why Michael would go to the island (to atone for his sins) — but not any of the whys that really matter. There’s no reason for these questions not to come up, no reason for Michael not to want to know the answers. The show just ignores them.
The same thing happens in the beginning of the episode, when Locke tells his people that he’s discovered that the boat crew intend to grab Ben Linus and kill the island’s inhabitants. Not one person asks the obvious question: Why? What would motivate this sort of mass slaughter? And why, in specific, do they want Linus?
Instead we get a lot of what and how answers: How Michael finds himself on the boat. What position Locke is taking as a result of the revelations. This is a pretty common pattern. Season two ended with a spectacularly useless revelation about how, exactly, Oceanic 815 was knocked out of the sky. It tells us a lot about what occurred, but after three and a half seasons, very little about why.
