Audio problem: When the little girl is dragging her sister across the room to get her to meet Sam at the pool, she says, "He's waiting at the pool for you," but her mouth doesn't even come close to mouthing those words.

Revealing mistake: At the beginning of the show they go to great pains to show (on more than one occasion) the "reflection" of Sam in the mirror. However, when the girl shoves him against it, kissing and slapping Sam, it is his real reflection.

Continuity mistake: At the end when Sam punches out the bad guy, there is not a white piece of trash stuck to the back of his left shoulder. Two shots later, there is a white piece of trash there.
Answer: Sam threw items off the raft to lighten the load, so it wouldn't sink, in doing so he made the raft less heavy. Which made easier to float with the currents, if it was heavy the raft would have moved slower and not moved so far.
Except that Al said that immediately after throwing stuff out of the boat four hours passed and it was shown that they didn't really move from where they were. They were still in the same spot. Forgot to ask this too. When Sam and Vanessa are stranded on the island, one of them, can't remember who, did something and when Al appears, he tells them that because of it, time had suddenly skipped several more hours and if the event hadn't been interrupted, they would have been rescued by a boat. So, what happened on the island that once again caused time to speed up? It seems kind of strange that time could move so quickly on the island, especially since it was still day time and it never showed any sort of changes like the sun or clouds moving.
