Banned Episode: The episode of the first season titled The One-Eyed Idol/Fifth Avenue Phantom is occasionally left out of circulation as it contains a lot of content that would be considered racist and sexist these days.
Dawson Casting: Paul Soles was 37 when he began voicing the teenaged Peter Parker/Spider-Man, and 40 when the show ended, resulting in some Vocal Dissonance for Spidey.
Keep Circulating the Tapes: Zig-Zagged: This show did not receive its own DVD until 2004. When the DVD came out, it actually contained all the episodes (a rarity for cartoons in Disney's library). However, this set went out of print after a few years. Later, the cartoon became available for digital streaming.
No Budget: Like other Marvel adaptations of the time, the series was produced on the cheap, and went steadily down in budget as time went on (the animation team even had to flee their creditors while producing the third season). Most fans, though, argue this adds to the charm of the show. In addition, no matter how bad the animation may have been on this series, it was much better than that seen on, say, The Marvel Super Heroes, which literally just took the (admittedly awesome) comic book art and only made the mouths move.
