In other words, you only get one movie or episode of your favorite show before all movies and shows are eliminated from existence in a solar flare or something crazy, what is the show you want to watch as your last one? So this question is a little different from just saying what your favorite movie of all time is.
I'll probably stick with the one I chose from the linked thread: Shawshank Redemption, but I'm probably forgetting another movie I would probably prefer to have as my last movie ever.
