Whether or not you watch Lost or not, as with most things, half of the audience loved the series finale, half were left wondering, and in the dark.
I think the following (taken from a blog post online) sums up what half of the Lost fans thought about the finale. So eloquent.
"That was total bullshit and totally predictable. So wait - in purgatory you can have a spinal injury, a son, win the lotto pay off cops, get arrested, murder people - oh wait until you remember your real life…yeah right…I wasted 5 years watching this to find out nothing - no mystery answered just some happy oprah spiritual horse shit? Eff Bad Robot Shows - I am never going to watch another one again - I am dropping fringe screw any star trek sequel or that monster movie…screw them"
