Like I said before,the Nikki Paulo storyline,if nothing else, was a device to buy the writers a little bit of time to figure out their next move.I'm still not 100% sure if they are really dead even though all signs point to the fact that they are.In the end,even though I liked that story,it was pointless to the plot of the show.
And again about Walt,they were trying to make it like he had some sort of power and now there is absolutely no focus on that.It's just like in professional wrestling when they make up some lame ass storyline or character and all of a sudden, they drop that story or that wrestler becomes another character and you're just supposed to forget about it.It's almost the same thing.
The whole thing with Mr. Eko illustrates this perfectly,hell,all of the survivors from the tail section(with the exception of Bernard) you could say this about.They ended up dead and now the only reason any of it matters is to give Micheal motivation for redemption,but looking back at it,they could have put anybody in the position that Micheal was in on the freighter and it really wouldn't have made any difference,thus,ultimately making all of the characters from the tail section (again,with the exception of Bernard) pointless.
And another loose end,Libby in the nuthouse with Hurley.They ended that episode like it was supposed to be some reveling aspect of the story that would effect future events,but that whole thing just whithered away without any fan fair.
Sorry dude,I totally understand where you are coming from,but I just don't agree with it.
