Well, I identify with Mamoru, and would expect most of us to do so.

When he gets to travel back in time, rather than looking at the media, or the currency, or asking people repeatedly, he runs to a computer shop to see "Okay, so the model with 3.5" drives just hit the market, that proves it's 1985!"

My dad is like a walking encyclopedia of mid-century automobile knowledge, I'm sure he can do the same thing with cars in old movies.

Luxury! When I was a kid, my dad tried to get my siblings and me to learn the wheel configuration of various locomotives.

It's just occurring to me now that before he passed away, I should have asked why the heck he wanted us to do that :)
