I am planning a rewatch of LOST too, but I don't have much time unfortunately
By the way I am binging Downton Abbey (I am at season 4), if you never watched it you must do that, it is a masterpiece drama, probably the best UK show for me! (MAGGIE SMITH RULES EVEN TODAY!)
Watched and dropped Ascension almost quickly, so dull and silly...
I am planning to proceed with Falling Skies (season 3), and I have just started Fringe, great one so far!
Everything for filling the emptiness left by Colony, which will end its first season this Thursday *me starts to wait until 2017*
