TrueFilm: An in-depth discussion of film

Good actors and character development, classic underdog story, the music is also great...what's not to like? It doesn't need to be historically accurate to be entertaining. Braveheart is a great film but 0/10 for historical accuracy.

why all the love?

NEVER ask this question decades after the release of any product. Never.

You're missing all the context and the circumstances surrounding the release. You don't recall what alternatives were available back then. You no longer feel the atmosphere of "these days".
