Personally, I have no problem with the rating being lowered. With clever editing and context, bloodless stabbings can be made to have as much impact as super-bloody ones. Take the Lord of the Rings movies, for example. Lots of stabbings, decapitations, etc, and in many cases, it has lots of emotional impact, despite the pg-13 rating. Admittedly, blood can sometimes give a film that extra oomph, if you will, in a case such as Logan, but it can also land you in a situation like Titans, where it looks stupid. As far as superfluous cussing/inappropriate content, that’s rarely essential to the story. This isn’t Deadpool. Also, again, an MCU crossover would be great. Tom Holland’s goofy nature as Spiderman crossed with this Venom’s fear inducing personality and dark humor could be great.
Wow, sorry for the long post!
