I haven’t watched Lost, but there is a nice review in the online version of Tricycle magazine , a Buddhist publication. The author, Dean Sluyter, is a Buddhist practitioner who has written a book on Buddhism in cinema. At the end of the review there’s a link to his website and the book.
I remember several episodes of The X Files , that had Buddhist references, and they are all neatly together Here , along with some other TV references.
