Actually, he was in two episodes, and the Daily Bugle still played a rather large part. However, while this would be a new way to go, it might be interesting. After all, Robin has played a long and important role in the Batman mythos, yet that doesn't affect stories that choose not to use them. In an age where not as many kids get jobs during the school year, I think it won't affect the Spider-Man story. Besides...I'm almost scared at the list of good actors who've played JJJ. How long can they keep that streak up?
