The REAL best answer is the Superboy TV show.
Sure, being Superboy he doens't get to have Lois or the Planet, but the core of the character is there, especially Season 2 onward. Gerard Christopher might be the most underrated Clark actor.
Lois and Clark is fine, but it does feel like they didn't embrace the comic aspect as much as the superboy show did. So many episodes feel like they could've been one-off comic stories from the 50's-70's.
It's a shame this show is so burred these days.
