Yes, I'm addicted to "Lost", and "Desperate Housewives", the only two shows I NEVER miss.
I was so angry and disappointed that they killed off Eko -- he was a great addition to the cast. On the other hand, it does lend to the belief that they will kill off important characters -- Shannon and Boone, and now Eko. But, IMO, that was a waste of a great actor and a well developed multifaceted character. I like Charlie, Claire, and Bernard but, IMO, any of them would have been less of a loss as far as the plot lines and the quality of the cast. If they think the two new "pretty" characters they introduced are going to replace Eko, I believe they are grossly mistaken.
I hate that they used the "Smoke Monster" -- too SciFi for me. I suspect the show creators are using it as a metaphorical Devil -- another play on the light/dark, black/white, good/evil theme. An unrepentant sinner lost from God by choice and taken by the Devil. Though I personally did not see Eko as a "bad man" and agree with his assertion that he did the best he could with what he was given.
Uh-oh, you got me started on "Lost".
