My concern is a plot change. I have to assume you’ve never seen this show before.
In Broadway, there was never a single mention of any “dreamers” aka- illegal immigrants- “getting kicked out”.
But whatever makes you feel better.
I haven't seen it. But I follow musicals, so I actually know a bit more about the narratives of them than the average bloke. My thoughts on it are really just more generalized based on a pretty surface level understanding of the show. I also write and studied literary theory, so I feel "keyed in" to the messages of artistic products.
There's three things to consider:
1) the actual plot and themes of the show is about desiring a and sacrificing for a better life. That's the conceit. All discussion around the show's narrative (and any changes to the show's narrative for the movie) will focus on adhering to that plot and its themes.
2) Movie adaptations of stage musicals tend to be far more direct and unsubtle with their messaging. It's actually the source of most complaints related to movie adaptations. We're seeing it with Cats. We saw it with Phantom and Les Mis. Nuance and abstraction in the story-telling is avoided in mass-produced musicals. Like "In the Heights."
3) Art, all art, isn't developed in a vacuum. And that matters because the musical was written over a decade ago in which so much as changed in our society. Those changes, change the art.
The thing about Lin-Manuel is that, aside from being a fairly average actor, everything he creates is made with HIS purpose and point of view in mind. He's not a fluff. And he's remarkably direct about his messaging. So, when I say that messaging was always there and that they're just making it explicit, I say that because it's exactly what we should have expected from everyone associated with it.
