All these leaks seem to confirm the same things. I feel like we know already the entire plot by now. lol...It really rubs me the wrong way that they have chosen the Skrulls over the Shi'Ar. I really don't get why. They could have easily update the Shi'Ar's appearances and make them look more "otherworldly" and give them image inducers or some alien tech to hide their true appearance in public. The Shi'Ar and their complicated relationship to the Phoenix Force and Jean Grey is such an important part of the X-Men lore!
I would have also loved to see Jessica Chastain as one of the classic and iconic X-Men villains like Emma Frost, Mrs. Sinister/Mr. Sinister or (Lady) Mastermind. But I have no excitement to find out that she is a green skrull queen. The only thing that gives me hope is that Chastain could also be Mrs. Sinister is the end credit scene of Apocalypse, that Chastain uses the term "clinical" and a vet metaphor to describe her character and the pale skin of her appearance...I'm praying to the Shi'Ar gods that she is not a Skrull...
Honestly, if they would liked to have used a green shapeshifting alien race infiltrating earth they could have easily chosen THE BROOD!
All of these options are more fitting then shoehorning the skrulls into this movie. I am also wondering if the big reveal is that Mystique is actually a skrull and not a mutant. Gosh,...at least let it be Beast. His character is so boring and bland that the big reveal that he was replaced by a skrull infiltrating the X-Men years ago and imprisoned somewhere would at least redeem him for future movies...
