I finally rewatched the whole 'Lost' series with my kids last month
We did it over a long weekend in April, just plowing through seasons 2 and 3 back to back. It was wild seeing their faces during the big twists, like when the hatch opened. The best part was how into it they got, asking a million questions between episodes. Anyone else try sharing an old show with a new generation and have it actually work?
The hatch reveal still gets me every time, too. My kids went through Battlestar Galactica last winter and it was the same thing - nonstop questions and rewinding to catch details. Just let them binge at their own pace and don't try to explain everything at once, half the fun is them figuring it out themselves.
