I used to not like the stories. But once I got around to the fact that he was virtually invincible, yet his weakness (or strength) was that he wouldn't kill anyone and always had to reel in his strength to keep from really killing someone, then I got more into the stories.
There was an early episode of Lois and Clark where he almost quit. Luthor would send out many attacks against Metropolis at one time, and Superman couldn't stop them all at the same time. He found that when he quit, Luthor quit, so by not being a hero he was saving lives. Yet, he was still needed. He realized that he couldn't save everyone, and that was the price he had to pay to save anyone.
Anyway, I'm much more of a Superman fan since. Digging Batman as well. Love the DC animated universe (especially Justice League and Justice League Unlimited)
