Bingo "I hate show tunes" wings:
I've never met anyone too old for time travel.

Unless you're Dur, apparently.

This is what I meant:

When I got the DVDs a while back, I was watching some of the BTS stuff, and enjoyed the Bobs talking about where the ideas came from. Gale said that the genesis for him was looking at his parents' High School yearbooks and realizing that they were once teenagers and had their own High School experiences. As he looked at the pictures, he wondered if he could have even been friends with his parents, or if they would have settled into different cliques.

I find that the first movie works best for me on that level now... the teen who meets his parents as teens... but for my son it works best on this level:

TIME TRAVEL IS COOL!

I still (a little past 28, but regardless) think that time travel is cool and all... but the movie means a lot more to me now than it did then.
