I thought the same thing as your spoiler the second Jacob told Hurley what to do.
The stretches for me? Julia being alive at the bottom of the hole miracuoulsy unhurt by all the debris, let alone surviving that fall to begin with. Jack trying to give CPR to Sayid, despite having said there was nothing he could do to savie him with the gunshot injury. The lack of traffic at the LAX restroom, and the security not setting up a perimeter first. Just poor writing.
Love this show, but this episode just felt silly at times.
