Here's some more examples
- In the "Sinister" Six episode(I think it was that one), Spidey's crawling up a building, it then suddenly shows him crawling up a sewer pipe and then back to crawling up the building.
- In the second season finale, Spidey's fighting the Scorpion. Not only was the same shot of Scorpion charging at Spidey used about two or three times, that shot was from his debut episode. Which was after he started mutate into looking more like a monster instead of just a man in a scorpion costume(which seemed to have been dropped afterwards).
- In the Venom/Carnage episode, when Carnage breaks out off Ravencroft, you see Venom escaping instead.
The animation was goof in the first season(especially Night Of The Lizard), but it's quality started to go downhill in the second season. And it got worse as the show went on.
Now yall done got me started lol.
