@Cube: You're right about Batman, but Spider-Man is written with a hyphen. The reason for the hyphen was to differentiate him from Superman. Because at quick glance, Superman and "Spiderman" look very similar. But the hyphen makes Spider-Man stand out.
Agreed with ROJM. I liked Superman Returns, but it did make some stupid decisions. All that is a plot and film problem, not a character problem. In previous Superman discussions I've given a number of great examples of Superman:
Comics: There are hundreds, but if you want a fantastic mini-series I will once again give a shout out to:
Cartoons: The 1940's Fleischer Superman cartoons are CLASSICS. Great animation, fun stories involving scientists, robots, WWII, etc. Not deep by any means, but a load of fun to watch.
Superman: The Animated Series. From the team behind Batman The Animated Series. Need I say more?
Movies: I'll admit, the 70's Superman movies are dated, but they did a LOT for the superhero film genre. The first is a great film. Origin story is told very well, the score is fantastic, the effects are great for the time and it's got Brando and Hackman! THe sequel is a good film as well, though I prefer the Donner Cut.
The upcoming Man of Steel looks to be good, though I don't know enough about it yet. Just that it's a reboot and features Zod.
