LOST SEASON THREE ENDS
In a two-part, plot exposing, question-raising, action-filled, betrayal-seasoned episode which reminds us that knowing everything isn't really what makes a show fun. Lost still stands out for me as one of the few shows where the characters actually do develop and have character as the episodes progress.
And best of all, it ain't over. The show is to have its final episode on 2010, which means, more fun for me!
(by the way, that is an image of season 2, but I kinda didn't want to spoil anything for anyone else who still likes the show.)
