1977-Amazing Spider-Man

Ah, yes. My favorite show at the time, well, this or Wonder Woman.
This show gets props for being the first live-action attempt at Spider-Man (Electric Company skits not included) and was part of a late 70s superhero tv fad.
Although it seemed to be a halfway decent attempt at the character, it quickly became a typical 70s tv show. Most characters from the comics were never used and key story points were changed. No super-villians ever showed up and Peter was stuck fighting 70s crime.
Stan Lee is reported to have not liked this adaptation, which did not help it's public perception.
Only 12 episodes were produced and several were doubled up and syndicated as tv movies for years.
