Come on man, Venom shouldn't of been PG-13 and Carnage should absolutely not be. That's an R character for sure. All two of head biting scenes are off camera and there's no blood or bodies on ground afterwards. Everything is so domesticated. All neat and tidy. Don't want anything dangerous or frightening to people. That's Not Carnage.

Doesn't help that the rest of the movie was a mess also.

One plus is Venom was somewhat funny.
