Not just because it was so good, but also so accurate to the book (in terms of dialogue etc).

Obv a merely feature-length film would have to cut more, but there's no need to actually change lines. There were several glaring mis-quote from the book merely in the trailer, which is why I didn't bother seeing the film.

It's not just that I know how it should go and don't like it being changed. It's also that, you know, Austen is doing clever subtle things with the dialogue. Changing them is daft.
