Sony wants to make a Venom movie. A Venom movie that doesn't take place in the MCU, didn't they just reboot Spider-Man to make him fit into the MCU? What the hell are they thinking over there? Ok look, Venom is one of my favorite characters. There is not another character in the Spider-Man lexicon that I care about more so maybe I am a bit overly protective of him but can you blame me after Spider-Man 3?
Sony forced the character into that movie against the wishes of Sam Raimi and look how that turned out. He was nothing more than a evil Spider-man when the character is so much more than that. It was as bad as the X-Men movies. Almost as if someone just flipped through a comic book saw a picture and said lets do that with no care given to the heart of the character. Sony can't do that again!
If they want a Venom movie, and we should have one, then what you do is simple. You set him up in the Spider-Man movie and spin him out like that. It wouldn't be hard and it would have a connection to the MCU which would give it a huge boost in the eyes of the fans. Plus Marvel won't let you mess with their universe so they will make sure it comes out good. And isn't that what we all want? For it to be a good movie that the fans love and Sony makes money off of it. Everyone wins, why is this so hard?
If Sony is dead set on making a movie outside the MCU using Venom than there is still a way to make this work. Don't use Eddie Brock. Now you might be saying what the hell man? How can you make a Venom movie without using Eddie Brock? Use Flash Thompson instead. Instead of going with the bulky Venom, which they should have used in Spider-Man 3, make Agent Venom. Make it a spy series instead of a superhero film. People might not get it right off the bat but if you make it good it could work. It's the only way that people will go along with a Venom movie outside of the MCU.
I guess the key is to stay as far away from Spider-Man 3 as you can.
