I've just become an instant fan of this show, thanks largely to the Season 2 set. There were some really entertaining episodes that year! In addition to the ones mentioned above, I also love Around The World With Superman and Shot in the Dark.
Naturally, I had to pick up Season 1, which I'm enjoying equally as much. However, I do think Superman was put to better use in the second season. Despite the first year being uniformly good, there were more than a few episodes where Superman wasn't really needed, imo. :wink:
Of course, that could also be due to Reeves' Clark Kent being interesting enough to carry the entire episode himself.
- The Dog Who Knew Superman (one of my favorites)
This was a fun show as well. I love the scene where Superman is leaning casually against the wall, smiling at the crook's foiled plan. When the crook suddenly acts as though he will hurt the dog, the look on George Reeves' face is classic. (It's very, "Man, I WILL kick your ass!")
