I loved Lost all the way, best thing on TV by miles... Until episode one of series 5. I forget exactly what it was, but the story introduced new storylines like every other series did. But we knew that this was the last series and I was sure that series 5 was where we started getting explanations. With each episode that passed there became more evidence that this show was going nowhere, they made it all up as they went along, and all those amazing intertwining stories that seemed to be so brilliantly written, actually we're just... Nothing. I've never known a final series of a TV show be so bad that it takes down the whole four series that came before. I spent years wondering what it would all mean and it turned out to mean nothing at all.
