I haven't seen the film yet, either, simply because I live in the United States and it did not premiere until today. That being said, I'm seeing it tomorrow, and I honestly am equally apprehensive and excited to see it. Crimes of Grindelwald left me with mixed emotions, but the largest one is complete confusion by Queenie's decision to join Grindelwald. That was absolutely the last thing I expected from her. I think there is a part of me that can understand her desire to just be able to be herself and be free to marry who she wants (ie. Jacob) , but I still never thought she would abandon her sister like that. I'm going into the film with an open mind and a hopeful feeling, but there is a large part of me that just hopes they fixed what (I feel) they messed up in the previous film.
I can say, though, that I've seen a lot of people saying "there's absolutely no way that Creedence is some long-lost Dumbeldore brother!" like he was told by Grindelwald, and while I agree with this - we have a fairly well-known layout of the Dumbledore family's childhood and such - that doesn't necessarily mean that he can't be related to the Dumbeldores in some way; from what I've seen, Grindelwald doesn't necessarily outright lie, so much as twist and manipulate the truth to his own advantage. I think that's one of the most dangerous things about him. He knows exactly how to manipulate people to do his own bidding.
Speaking of Grindelwald's manipulations, this just brings me back to the idea of Queenie joining him. The more I think about it (while writing this out) the more I can see how he managed to convince her to join him. The man is extremely manipulative, but he's also incredibly charming and charismatic. He knows what he wants, and he knows exactly how he can achieve it. Grindelwald knows that with someone like Queenie on his side, someone who is equally charming as well as a powerful Legilimens, he can get much further in his plans than without her.
As for her legilimency and using that to see through Grindelwald's plans to his ultimate goal (one she would never support), I have no doubts that Gellert Grindelwald is a very gifted Occlumens. We saw Voldemort try and fail to penetrate Grindelwald's mind when he was in Nurmengard in 1998, and that was 53 years later; you can only imagine how much stronger he was when he was younger and in his prime. So when others ask how Queenie didn't see Gellert's true intentions, my best guess is that he is protecting his mind from her with occlumency. Combining his status as an Occlumens with his manipulations and charisma, it's honestly a bit surprising that he didn't have even more followers than he did.
With all of that said, I'm more excited than anxious about Secrets of Dumbledore, and I am just counting down the hours and minutes until I see the film. It's 20 hours, 39 minutes, and 20 seconds as of right now. >.>
