EW.com just posted a cool article explaining briefly what Lost is about and comparing it to the cult TV shows that came before it. From The Twilight Zone and the Outer Limits to The Prisoner and Space: 1999 (Two shows I have never seen). It also recommends some novels that someone with who is a fan of Lost may want to read. (I personally can highly recommend The Stand and the Dark Tower series, and can also say that I read about 100 pages of the Third Policeman and stopped reading because I did not understand anything that was going on in that book.)
Feel free to read the article by clicking here and enjoy. Unlike most other Doc Jensen articles it is short and it may give you some ideas of things to watch/read during this slow summer season.
