Plot Ideas for an Amazing Dr. Strange Movie

I've been getting really excited about Doctor strange and reading up on some old Strange comics I had in my attic. And decided to throw out some ideas that could make it a really good and would fit into the Marvel comic universe.

1. Don't do an origin story
Do it as a huge fight between Dormammu and Strange and do the Origin as flashbacks. This I think is hinted at because as of Winter Soldier Stephen Strange is already on Hydra's radar as someone that can do some damage. So we have to set it in the now in the Marvel Comic Universe and I think this should be after he has established himself as the sorceror supreme

2. Change Mordo
I love Mordo because he's always bad and you know him. But i think we need to modernize him. I think make him a friend of Stephen Strange the surgeon. Have them be old friends from college. Mordo is the one that tells Stephen about the Ancient One. Mordo helps train stephen and they actually become really close. It  isn't until Strange becomes the favorite of the ancient one that Mordo turns on him and kills the Ancient one forcing Strange to become the sorceror supreme. If they want Dormmamu you could have Mordo basically let Dormmamu out of his cage and then really need Strange's help to put him back. Also instead of Mordo being a European Baron, make him a wealthy businessman. He could also be a Baron. But being a Baron doesn't mean that much.

3. Say that the goofy robes have powers
They need to explain that the robes have powers and thats why he wears them other wise it doesn't make sense. The robes are cool in comic books but they look ridiculous. Since everything else he has has powers attached lets just say that's why he wears his silly robes too other wise he'll just look "strange"

4. Dormammu needs to be really powerful
They need to explain that Dormmamu is too powerful. That if he was able to fully come to our world he would easily take over and destroy everything. Dr. Strange, and the great thing about his comics is every volume he saves not only earth but our entire demension. He saves our entire realm in every volume and Dormammu in the early comics is really scary. He needs to be super scary and powerful. AND NOT A HUMAN DUDE!! My fear is they will get some super handsome actor to play him and he will be a good looking guy in a black suit. If they want to do that with with Mephisto I don't care but you can't do that with Dormammu, he's not a human and he's the leader of a hell demension. 

5. Introduce only the best characters
I think they can use Wong as a character to explain Stranges odd world. Or they can have him take on a student. They could have Scarlett witch as the student but it might make more sense to introduce Topaz as his student. But Don't over load us with a bunch of characters. he's going to reference the Vishanti, he'sgoing to refference Cytorrack all kinds of strange stuff that audiences don't need to know. But what they need to know is the only thing protecting us from these dark powerful demensions is Stephen Strange and there are other people using these powers for Evil. Karl Mordo, Nick Scratch and others.

Tell me if you agree. Add any other story Ideas you have.
