Some of the episodes were taken right from the comic books(such as the one where Jameson sends a robot with his face on it after Spider-man--it even used lines directly from the comic). Others were rip offs of shows from Rocket Robin Hood(in particular the "Dimentia Fiiive!!!" one). These were the worst ones because they tended to meander and frequently had these psychedelic background skies that were really depressing to stare at.
It was a good show for laughs--intentional and otherwise. Whenever I read a Spider-man comic--I think of J. Jonah Jameson, Peter Parker, and Spider-man with the voices they have in this series.
Note: the music was actually pretty good--very fast moving--and of course the title song with its memorable lyrics: "Spider-man, Spider-man, does whatever a spider can, can he swing from a web? Take a look overhead, hey there, there goes the Spider-man!"
Once you hear that song--you'll never get it out of your head.
