TV on the Web: Lost

The final season of Lost will begin in January, bringing to a close the journey of the survivors of Oceanic 815. Whether you've never gotten around to digging into this dense ensemble show or you'd like to revisit some long-forgotten episodes, you can now watch the first four seasons on Hulu.

In case you've been living under a rock for the last five years, Lost begins with a commercial flight crashing on a tropical island. In the two-part pilot episode, we are introduced to a large group of characters who have survived the tragedy. It doesn't take long for them to realize that there's something (or rather, a lot of things) very odd about this island.

Unfortunately, only the last five episodes of the fifth season are available on Hulu, so you'll have to catch up with the majority of that elsewhere.
