They ruined Venom. Just sayin.
Can you tell me what happened?
Venom in this series, believe it or not, is actually Spidey's blood. Doc Ock got a hold of it and "increased the darkness", creating the "Venom symbiote". Looking for its origin, the "symbiote" arrives at Harry Osborn's party. It bonds with Flash Thompson (which I'll admit is pretty cool) and attacks Peter. It then bonds with Nova, Power Man, Iron Fist, and then finally Spider-Man before they destroy it. Later, Norman Osborn and Doctor Octopus plan to make an improved version of the prototype and it is also revealed a sample survived, which is then found and trapped by Harry in a bottle.
You do know that in the comic Ultimate Spider-Man, that's not far off from what was in there. The Venom symbiote in the comics was supposed to be a cure for cancer creater by Richard Parker (Peter's dad) and Eddie Brock's dad. They used Richard's blood as a base for the formula, so that's why it melded with Peter so well, and was so intent on him being one with it so much. It actually makes a lot more sense than some random alien costume attaching to him, and randomly wanting to be one with him.
To the original point of this, I liked the show. It's pretty funny to me. Drake Bell is a really good Spidey, and having Fury put together a young Avengers is a really good idea. It's not the greatest Spider-Man show ever, but in my opinion, it's the third best Spider-Man show. (First and Second being the 90's Spider-Man, and Spectacular. In no particular order.) It's certainly not the worst. The worst Spider-Man show is the 70's live action show. (other Spidey shows that are worse include Unlimited, the 60's Spider-Man show, and the Japanese Spider-Man)
I am well aware of Ultimate Venom's origin. As for the show, it is slightly below adequate at best.
Why do you think the show ruined it then? We can agree to disagree on how good or bad the show is, that was just my opinion
