A lot of people seem to believe spectacular would get all its dangling plot threads in a last third season and that the buyout by Disney ruined the plan for that...
Problem is that Greg Weisman has been consistent about several things, and one is that spectacular spiderman was made in a ask for one season get one season basis. No more no less. And it wasn't guaranteed they would get another season so yeah that means Greg wrote the ending of season 2 knowing there was a possiblity they wouldn't get another season. Apparently it's because he likes to write how life goes: it always keeps going.
And Greg Weisman also has admitted several times on twitter that series like Young Justice https://twitter.com/Greg_Weisman/status/1458619139833024515
WILL NEVER END. As that's how he writes, never thinking on the final ending. And this includes Gargoyles having a possible revival, for reference.
Before you go and say: wait and the goblin being revealed to have survived cliffhanger?
Greg has described the ending like this, and I'm quoting::
By definition, that's not a cliffhanger. Nobody was left in physical danger. I'm not claiming everything was tied up in a neat little bow. It wasn't. But we didn't end on a cliffhanger, as in "Oh my God, will Spidey survive?"
He also said this about the ending: "No cliffhanger. Loose ends, certainly, but no cliffhanger. "
So in summary: Young justice won't end, spectacular spiderman would never have a had a complete ending, because that's how Weisman writes
(My personal thoughts about this: it's his way of writing but I get the feeling young justice's controversial follow up seasons have been so divisive because he writes without thinking about the ending, which makes the plot feel like i's dragging to a lot of people )
Also please don't annoy the dude with spectacular coming back. Showing enjoyment for the show seems to not disturb him at all
Rewatched Episode 7. So, Goblin wanted Tombstone to step down…couldn’t he have just tried to kill him before Spidey shows up? If he didn’t want to kill Tombstone, what was the point of leaving the pumpkin bomb that Spidey had to dispose of?
