Would you agree it was a bit toned down?
I think it was undertoned because it's called Fox Kids there for they couldn't do anything as extreme in the comics.
Instead of the Sinister Six they used Insidious Six.
Green Goblin (Norman Osborne) didn't get to kill Gwen, or Mary Jane.
Carnage was insane but he couldn't be as graphic, and murdurous as his comic counterpart.
Punisher didn't get to kill scum in his guest appearnces. I liked that they still depicted him close to his comic counterpart, and remained a straight shooter.
Spiderman wasn't allowed to punch. I don't understand this because he was shown doing super kicks.
Feel free to add anything I missed. It was still not overly undertoned. They showed Venom as a scary revenge seeking super villain focused on killing his hated enemy Spiderman, Hydroman was depicted as a threatning super villain that just didn't give up on getting Mary Jane to love him who was not interested at all. In the Alien Costume episodes Spiderman was acting more violent, arrogant, and Peter Parker was having trouble with getting along with people when he wore the alien costume. Mysterio like his comic counterpart worked in Hollywood, and was aiming at getting revenge on Spiderman. Add in his wisecracks.
