I was satisfied with the ending. IMO, it would have been better if the sideways world was heaven, but then again you wouldn't see Sayid acting that way in heaven. Remember that the sideways world took place in the future, hence Hurley's comment to Ben, "You were a good #2" and Ben's reply, "You were a great #1." Perhaps some of the missing people from the church did things after they got off the island that did not deserve a ticket to heaven, or maybe they weren't ready like Ana Lucia. (Were Lapidus or Alpert ever in any sideways world storylines??) Reference Michael, Harold Perrineux was on the Lost Reunion on Jimmy Kimmel and said that Michael is stuck on the island for eternity. I too was disappointed with no resolution with Walt. Also, what did Widmore whisper in the Man in Black's ear? After the Kimmel show went off the air, the cast did a Q&A that is supposed to be available on Hulu. EDIT: I forgot to add... I'm pretty secure with my masculinity, but all of those reunions got me teared up. Claire and Charlie was the worst for me.
