I am an unabashed J.J. Abrams fan. I watched Alias for years, even when it went insane and everyone (especially the writers) lost the plot thread, and I am a (charmingly) rabid Lost fan. Because it is the greatest show, in the history of time. Eric disagrees, and I recommend that you leave anti-Lost comments on his blog, because I will not support those shenanigans here.
There are a ton of details to sift through, and Flavorwire very thoughtfully put together the best books from Lost, in terms of literary-ness, not Lost importance.
