Here is a link to a review that (more or less) sums up my POV on the lost season finale.

A lot of people in internet-land seem to think that “not liking” the ending of Lost somehow equates with “not understanding” the ending of Lost. I got it, alright. I just didn’t think that Alternate U added much to the overall story except for a narrative excuse for the classic “clip show and cast hugs” season finale. I didn’t need to know the answer to “Why does the Hurley bird exist?!?”…but I sure as shit didn’t need a “Spontaneous Holographic Buddhist Karma Wheel” tacked on to half of the last season so the writers can cram some “people are all that really matters” obviousness down my throat. Shit works better as subtext, y’all.

Lost was still a fucking awesome show, btw, and that last episode was at least 90% good. I just think the last 10% shit its pants.
