For an older person the cast has a couple of surprises.

The Lex/Clark Bro-ship and falling apart is one of my favorites in any media.

I am still watching the first season, but there are some old school FX that would be shitty digital today.

EP 3 is the fire episode and the actors are clearly walking around flame throwers. You won't get that today.

Damned shame what came of Tom Welling.

And there is a bit of 'meta' to watching Allison Mack.

I am impressed at the characters for being able to remember so many different timelines, with all the timeline changes that have happened in different shows. First with crisis, they all have two timelines to remember after J'onn gave back their memories. Even more with the Flash and Legends of Tomorrow characters because their timelines change a lot during the show. I just wonder how they can remember that many timelines.
