I think for the modern audience, any book by Jane Austen makes a better movie than actually reading the book. The books are, essentially, comedy of manners, and good actors can execute that with glances and gesture far better than Austen can with pages and pages of description.
As someone who’s read the book several times I turned off the show halfway through the 1st episode and never returned. One of the big problems in the show was making Hazel the leader from the beginning. The point of the book was Hazel never thought of himself as the leader; he always deferred to smarter (Blackberry), stronger (Bigwig) and more insightful (Fiver) rabbits, to make decisions. The big payoff is when Bigwig stands up to General Woundwart [“My Chief rabbit told me to guard this run”] and you realize they all would risk their lives for Hazel.
