My only regret is that I watched the season five finale tonight...and now have to wait until Feb. 2nd.
Season five's finale was a serious WHAT. THE. FUCK. moment. Locke was dead, then alive, and now...kinda dead? Christ. Also, what will the bomb do? Kill them all? Be the catalyst that brings them back to present? Almost as good as season three's finale, which was fucking epic, and made my jaw drop to the floor, because I seriously had no idea.
In all, I think season two was my favorite episode. The hatch was a great story I think.
Anywho, so glad I watched this series. Can't wait for the final season...and I'm proud to join the group of avid Lost followers.
