Yeah, I can agree with that, since Peter's original reaction of visceral horror, i.e. "It's a creepy alien, get it off me!" didn't exactly paint him in the best light and made it a little too easy to sympathize with the symbiote.
Main one being that the Spider-Men and their supporting casts/allies were practically the only decent people in the 'verse, whereas damn near every other "hero," especially the Ultimates, was a bunch of jerks at best and downright psychopaths at worst.
