The push-and-pull between human host and the symbiote is part of what makes Venom such an interesting character, and I have long believed that this is the reason why Venom hires Tom Hardy in the first place.
But I’m personally thrilled that Sony and Fleischer kept that aspect of Eddie Brock’s torn personality, as it makes Venom look like more than just a CGI cluster-bang.
It would be easy to jettison this character trait, as explaining it to a mainstream audience presents a challenge.
Hardy is a fantastic actor who would be wasted if you didn’t give him some dramatic material to shew on — and then blessed him with CGI fangs with which to chew.
