Lost cocreator Damon Lindelof, discussing the appeal of the show:
"The island just serves as a conduit to tell character stories," he says. "No one is really watching the show for the answers to those mysteries. They're watching to see: Will Kate and Jack hook up?"
Lindelof apparently knows nothing about his audience. Pity.
Does anyone give a damn about Jack and Kate getting together, at this point? The showrunners have invested no energy in their 'relationship', there's no substance on which to build. Indeed, the lack of romantic energy on the show was only underscored by the drop-of-a-hat romance between Sayid and Shannon - unbelievable and a bit gross, a mere convenience to separate Boone from his sister a bit.
Attention Damon Lindelof et al.! We watch your show to see interesting characters (e.g. Locke, Jack, Sawyer, Jin, Sun, Hurley, Michael, Rousseau, pre-romance Sayid) do interesting things (open the hatch, run from a cloud of (nanobot?-)smoke, play golf). Jack and Kate making moon-eyes at one another is stultifying, and Kate's backstory (oh whatever crime did she commit?) points up the difference between intriguing and meaningful plot points. Unless makeout sessions on the beach resonate with the rest of the island goings-on and affect the social texture of the group of castaways, don't waste our time.
I watch the show because I like freaky universe-undermining cosmic mystery stories. And scary jungles! Doesn't everyone?
