I'm sure there have been movies to make me tear up, but TV show moments are the more memorable. For me, they include:
BtVS, the episode where Buffy finds Joyce dead. I don't know if I felt as strongly about it when I first watched it, but when seeing it years later on rerun after my father passed away, I *felt.*
Everything about that episode you can identify with if you've lost a close loved one.
And the other, more happier 'wet-eyes' moment of note, was the episode of Gilmore Girls where Lorelai proposes to Luke. When he's going on about how they going to get Rory back on the right path, and she finally realizes exactly how much he loves and cares for both of them, her just out-of-the-blue proposal gets me.
Finally, a meant-to-tug-at-the-heartstrings episode that does it's job well, is the Christmas episode of 'My So-Called Life'. For those who've seen it, no explanation needed. For those who haven't seen it, you should.
All in all, life experience changes you. Whether it's the loss of a loved one, or the joy of a new life, it changes you. And that's why we can see the same movie, years apart in viewing, and have a totally different reaction the second time 'round. We finally 'get' it.
