Things You Only Notice In LOST After Watching It More Than Once

Lost was a pretty out-there show that had so much intrigue and so much going on that it would have been almost impossible to notice every little thing while the show was first being aired. But when you rewatch it, there are things you notice, or at least begin to understand, that you were probably totally oblivious to the first time round.

Here are just a few:

• Remember that tidal change in season 1? The one we all thought was just a tidal change. That was our first indication of the island moving. We just didn't know it yet

• What about the US army knife that Ana Lucia found in season 2? It was a clear indication that there were US soldiers on the island.

• When the bodies of The Others were put out to sea and burned on a floating funeral pyre, it was more than just a ritual. It was a way of protecting those bodies from being occupied by The Man in Black.

• On second watch, it becomes obvious that the numbers 4, 8, 15, 16, 23 and 42 – which Hurley believed were cursed – were pretty much anywhere that numbers appeared in the show. Subtle, yes. But it's hard not to see when you understand their relevance.

• On the subject of Hurley, he was on the TV in the background when Jin went to send a 'message' in season 1 episode 17.

• And when Kate went to visit her 'real' father, Sergeant Major Sam Austen at the army recruiting station, it was Sayid who was on the TV screen in the background.

• Then there was that exchange between Sayid and Hurley in season 2 episode 13 while they were listening to the radio. Sayid said the signal could be coming "from anywhere" to which Hurley replied "Or any time". He quickly followed up with "just kidding dude", but the seed was sown at that point that there could be more to their situation than met the eye on a first watch.

Lost was one of those shows that had audiences gripped for years. Every viewer had their own theory about what was really going on and how things would end. When the finale eventually came, it split the show's fans down the middle. Some loved it, others hated it. Plenty were perplexed.

But watching it back and looking out for those clues about what was going on allows fans of the show to enjoy it all over again from a different perspective. It's two viewing experiences for the price of one. And that can't be bad.
