Hmm I think it definitely is intended as that sort of allegory though — otherwise how can the message be about overcoming prejudice? Prejudice against what? And yes, it's well-intentioned as I said, but, come on, in trying to tell a story about tolerance, they end up building this world where 'weak' and 'strong' are biologically distinct groups, and the message of the movie seems to be "yes, this is true, but we should look beyond these obvious facts".

Tbc, I don't even mean this as a criticism of the film — but these aforementioned aspects do tell us something about the culture at large, I think.
