Doctor Strange was once my fav. character in the MCU, and Sam Raimi did not do the character justice. He co-wrote the script and oversaw Waldron on the writing process, and It was clear that both he & Waldron were more invested in the character of Wanda whom they made the film's villain at the expense of Nightmare, an actual DS villain as well as giving her the main story over Strange while regulating him to a caretaker for America Chavez. IN addition to that, there was also giving him a retread romantic story where they brought  back McAdams' Christine at the expense of Clea who is the leading lady and Strange's true love in the source material.  

All of the bigger DS characters and their relations to Strange were removed to make room for the conclusion of Wanda's story which should not have been the main priority of a DOCTOR STRANGE film. Many reviewers of the film barely have any thoughts on Strange leaving the film because he was not given a compelling story befitting a titular character. He was just there. Wanda is the character people exit this film discussing. The titular character should not be so drastically overshadowed, uninteresting, and unimpressive. 

Raimi is an iconic director and is viewed favorably in the horror genre as well as his wonderful work on the Tobey Maguire Spider-Man films. However, it seems clear that he nor Waldron are right for Doctor Strange, and don't seem to think enough of him as a character to do him justice.  As a result, I am petitioning for MCU Strange fans to come together speak against bringing Raimi back for another DS film when the character & lore was clearly not cared about under his direction. Raimi has a big following and it's his fans who want him back for DS3 since DS2 was his directorial debut into the MCU. But if we, as DS fans first & foremost want a good story for DS3, it seems evident that Raimi is not the way to go.,
