The 90's series was essentially poor. Because the censorship was so over the top. Here (from wiki):
1] Not mentioning "Death", "Die", "Kill" or other words with a strong negative meaning. Death was to be avoided, leading Semper to skirt around the issue. "Destroy" and "destruction" were frequently employed as synonyms.
2] Many realistic guns were not allowed, and no firearms could shoot bullets, so instead they fired lasers complimented by 'futuristic' sound effects. This often led to scenes in which ordinary policemen wielded futuristic pistols.
3] Spider-Man was not allowed to hit anyone with his fist, however there were a few exceptions. In Episode 39 ("The Spot") in which he used his spider-sense to guide a punch through a dimension portal and knock out the Spot. He also punched the Scorpion twice in "The Final Nightmare."
4] No crashing glass was allowed. However, in Episode 43, when Spider-Man and Doc Ock were battling in Felicia and Anastasia Hardy's home, Ock accidentally smashed a glass window with one of his tentacles.
5] No vampires were allowed on the show. This created complications with the use of the characters Morbius the living vampire and Blade the vampire hunter. Consequently, Morbius only drained victims through suckers on his hands, rather than by biting them in the traditional vampire style on the neck, and rather than blood, his sustenance was referred to only as "plasma." However, the word "blood" is used regularly in non-vampire episodes.
True vampires later appeared anyway, primarily in the form of Blade's vampire mother, but they are not shown actually biting anyone.
6] Cletus Kasady a.k.a. Carnage was not a serial killer in the series, he was just a madman. Carnage never actually used his symbiotic blades to harm anyone, he was either stopped or dodged. He also absorbed people's energy rather than killing them outright. However, he has made a few references to attempts to murder. For instance, when Baron Mordo stated to him that he needed a few more life forces, Carnage said "Only a few? Too bad!". He also referred to his process of draining life force as "feeding".
