Since I worked 2nd shift for 6 years, I never watched any LOST episodes. After I got laid I started getting DVD's at the library, and started watching LOST in October. I watched the first 5 years in four months. I realized I have a major advantage over others who took 6 years to watch it all, and forgot much.
I have read
some of the comments on their Yahoo group, and their Facebook page (15,000+ comments so far). People either thought it was the greatest show ending ever or the worst. Most complained their were too many unanswered questions. I can tell you, most of those questions were answered, or hinted at in the four months I watched the shows last winter, but most people forgot them in the past 6 years.
Not sure about Michael and Walt, but the boy couldn't be shown this season, he is six years older and probably 6' 3", and taller then all the rest of the cast.
When they are at the church in the end, time does not exist. They have all died in their own time. Hurley and Ben said they were the greatest #1 and #2; they probably lived decades (centuries) on the Island after the rest left.
As for all the loose ends, the producers said the show was about the actors, and not about the "facts". Just remember the show for how great it (and the writing) was. Was life on the Island real? I think it is best if we never know the answer.
And maybe Hurley and Ben will have a spin off???
