I love/d LOST as well... for so many reasons.. I still haven't given up doing my Desmond impressions: "Pennnnnnnny!" Which nobody seems to remember or find amusing like I do..
Alas,
I've heard Game of Thrones is pretty great, though..
And Walking Dead is wonderful if you like zombie stuff..
I'm obsessed with Parks and Recreation.. It's not much of a drama but the character development is tops for a comedy.
(I love you TV!)
