Here's a take that probably would have been controversial in like 2014 but Divergent is a good movie.
I don't know about the book? I honestly have very little interest in the book, but the movie speaks to me as a neurodivergent "twice exceptional" kid who always had a lot of expectations projected onto me and then either proceeded to meet those in a weird way or fail for reasons that seemed completely incomprehensible, the story of someone being able to overcome and separate from a society that can literally get inside your head, and doing so with the help of others who can do the same, as long as they're aware of that twice exceptional status, will always hold meaning to me.
Being Divergent as an allegory about being neurodivergent in a neurotypical society (and also genderfluid in a binarist, cis-centrist, heteronormative society) and being able to survive and prosper because you break convention is not something I expect anyone who wrote the movie off as being yet another YA story about a girl who thinks she's special to get, but then again, I don't care for the opinion of anyone who cannot parse specialness narratives as being about marginalisation in the first place.
The movie also has an amazing soundtrack, Shailene Woodley makes a good call of not bothering to act like a sixteen-year old but rather turns up the young adult in her performance... and Four's actor is hot.
Divergent is a good movie.
