You LOST me

I was once a big fan of Lost. I waited with near-breathless anticipation for each week's installment, but now I'm not even fazed. I think they have overdone the character of the week theme, and have not explained enough of the mystery. With Stargate Atlantis, at least you know who the bad guys are. In Lost, you don't even know who the good guys are. I'm done, have a nice series (or move along and reel me back in, ABC!!!)
