Instead of "Across the Sea," they should have finished season 6 without answering much. Then later have a mini series type thing with only 6 or so episodes, and have each be an "Ab Aterno" esque episode. One for Richard, Widmore, Christian (I still refuse to believe it was MiB all along), any mysterious character that was never touched on enough. Then finally having the last one about Jacob and MiB. Not that I'm dissapointed with "Ab Aterno" or "Across the Sea" but it is obvious that some things were a bit rushed. I think if they did that they could have really took they're time with everything, tied up all the loose ends, and made it perfect. Not that it wasn't amazing already though. I'm not complaining here.
