Pride & Prejudice & Zombies: JB review

I recently saw the film, Pride & Prejudice & Zombies, which is based on a mash-up book of Jane Austen's story where they're also in a zombie war. It was okay but not good enough; with a PG-13 rating you'll hear bloody sound effects but not enough blood, nor is there enough zombie action, and apparently the undead still have a conscious? Honestly I'm not familiar with Jane Austen's work, but anyone who is, this would be recommended. B-
