I can't recommend enough watching LOST in this way. The storyline plays not like a soap opera, but rather more like a Greek Epic, like the Orestia (my theatre degree coming in handy once again)... It doesn't try to "catch you up" each week, but rather, simply continues to tell the epic story. And because I watched each episode back-to-back, sometimes 3 in one evening, I didn't spend any time hypothesizing about the many mysteries of the show - I just watched, took it all in.
I won't spend any time in this post going over all the cool spiritual symbolism that exists in the storyline, many others have done that much better than me... (I mean, come on, Jack SHEPHERD has a son named DAVID who is a musical genius and his significant number is 23.)
Let's just say that I'm enjoying it, and I am glad that I caught up to the pop culture epic before the series finale.
Do you watch LOST?
