getting lost

I have a love-hate relationship with the show. It's wonderfully written with a great story line full of suspense, conspiracy theories and intrigue that leaves the viewers craving for more. But it's frustrating to watch, as the dialogue continually shifts from the past, to the present and makes references to future events. All this time travelling is starting to hurt my head. I think I might need to rent the previous seasons and do a Lost marathon to catch up. Oy.
