Yes, yes and YES. At one point, Marvel was going in that same direction with 90s and the long lost series Spider-Man the New Animated Series on MTV, but.... Marvel decided to aim things solely at kids and since then, its cartoons have been trapped in Neverland. And I do not mean that in a nice way.
If I can be honest, I am one the few fans who hated Spectacular Spider-Man and as someone who followed the cartoons even after it, I feel like it did more damage to Marvel, Spider-Man especially, when it came to TV series than good.
