My favourite Spider-Man shows were the late 1960's series and also Spider-Man and his Amazing Friends. However, this was a decent show as well.
The animation techniques had evolved since the late 1960's series and there were some exciting villains in it as well. My favourite episode was where Spidey was shrunk by a villain called the Gadgateer. All the top Spidey villains were here-the Kingpin, Green Goblin, Doctor Doom etc.
This had the best written episodes of any Marvel series in my opinion and the animation was top notch for it's time.
Highly recommended.
Just one more point; Why do great shows such as this never get released onto video whilst other rubbish gets every episode released onto video?
