Teamwork is a huge theme in countless Hollywood movies. A rag tag group of misfits who has to overcome their differences and learn to work together is a classic movie trope.
I don't think this has anything do with trying to appeal to Chinese audiences.
Less complex (and less overall) dialogue designed to make it easier to translate is an actual example of trying to succeed in China.
The film was written by long time fan of the series, so one of the central themes of the series being highlighted in the film is unsurprising.
I sincerely doubt it has anything to do with China.
e: Augh, I missed changing the Star Wars -> Star Trek edit and now I can't edit; I have permanently lost nerd cred for making that mixup ;_;
"Ordinary People" is a blue-blooded American Hollywood film.
No, i don't think that you're reading too much into it. In fact, i like your analysis. I'll have to rewatch it, again. LOL
especially concerning "unity" vs. "FREEDOMMM!"
Maybe I am reading too much in to it, but it felt like a shift influenced by the additional target market of the East, and I don't see Hollywood as a source of affecting moral/civic unrest.
