It looks so good! Beautiful sets, costumes and cinematography. I love the way it's lit. It looks period but with modern sensibilities. What I've been looking forward to the most is how they've adapted the story, and it seems like a whole new script. I love that we get to see and hear things in this version that the 1961 film and the stage musical didn't touch upon or expand on. For instance, we see the Sharks lighting a candle for Bernardo's death.
I know the trailer was probably edited to showcase more of Maria's story because of Ansel, but I wish we would've seen some things from Tony's perspective. Also, I like that Black people are also in this and we see the Puerto Ricans aren't the only minority group that the Jets hate. That shot of Anita walking away from the police station (?) and then telling Maria "If you go with him, no one will ever forgive you" were everything! I felt like I was the one being scolded haha. Loved the shots of various musical numbers that were shown, including I Feel Pretty, America, One Hand, One Heart and what I think may be Cool (the shot where Riff and Tony struggle for the gun). I don't know why, but I have the feeling that the Somewhere Ballet will not be in this version.
In terms of whether they are hiding that it's a musical -- I don't think they are? There's singing and choreographed dancing. I think this trailer focused more on story and characters. In the Heights's trailers focused on the music, but you couldn't tell what the story was about.
