I just don't want any other symbiotes, Carnage is too much of a one dimensional character with no parallels to spider-man to be good in a movie. Besides, to have it be at all authentic, they'd have to get rob zombie to direct and bribe the MPAA. I mean, Venom's a character with some humanity at least, if you look at sam raimi's initial refusal to include venom, "lack of humanity", that pretty much applies to Carnage, not Venom.
