I enjoyed what I've seen of this Superboy! I need to get more of it on DVD; I used to watch it on DCU back when that existed, but I only have season 1 on physical media. Honestly John Haymes Newton was decent too, though his scripts tend to be pretty awful. But Gerard Christopher had that John Stamos curl in his lip! Now that was hot!
Honestly it would be cool to see GC return as an aging Superman. I doubt it would ever happen, but hey, we can dream.
