The Spectacular Spider-Man is considered by many to be one of the best Spider-Man animated TV shows, but the series was, unfortunately, canceled after only two seasons. More frustratingly, Spectacular Spider-Man was nearly revived in the best possible way only three years later, only for these plans to fall through, avoiding a return that would have connected it to two other animated Marvel shows that are similarly beloved by viewers and critics.
