If I wasn't already excited for this movie, this full-length trailer would've sold me completely.
From the previous trailers we've gotten a teaser about the beasts that escaped Newt's suitcase and are running amok around New York City and the race of recapturing them before they cause more damage. In this trailer, we're given more footage of the political side of what the movie will be centering around, particularly the conflict between the American Wizarding community and those who are non-magical (No-Majes), with the latter there being a radical racist/religious group calling themselves The Second Salemers who are threatening to expose and persecute witches to the public. Reading up on everything surrounding this particular plot, it has me very intrigued. Even though I'm still wary of how JKR is going to handle the American side of things, I'll be taking it with a grain of salt since I'm fascinated by this aspect of exploring the cultural differences of magical communities and how they operate.
Furthermore, I am utterly fascinated with Colin Farrell's character, Percival Graves. We only know the basic details and description of his character from interviews, but based on those things alone I'm pretty sure he's quickly becoming my favorite character of this franchise.
Some are speculating that he's going to be the villain, and while we shouldn't rule anything out until we've seen the movie itself, I highly doubt this is going to be the case. Aside from what I've read in interviews and what Colin himself has stated about the character, Pervical is a good guy and may take only on the antagonist role briefly as he opposes our protagonist. That is it. He is tasked with a specific job and responsibility as an Auror and the Director of Magical Security at MACUSA which he takes seriously, and from the looks of things from this trailer he might even be questioning certain moralities and ideologies which he has been conditioned to perhaps towards the end of the film once shit hits the fan, realizing that things may need to change within the system they're living in, as he says in his own words: "We've lived in the shadows for too long. I ask all of you, who does this protect? Us or them?" and "I refuse to bow down any longer", perhaps referring to not acknowledging their own existence living among No-Majes, and that their method of protection isn't really working as they think it is. I don't know, this is my personal interpretation based on the things we only know so far. Basically, he's not going to be the villain but rather someone good who is going to be going through certain inner conflicts about what is right and what he believes in. But overall I'm honestly really loving his character already, and he's probably the one I'm most excited to see in this film.
