This is kind of an odd adaptation because they truncate the romance and the scandal with Lydia while enlarging the role of Lady Catherine de Bourgh, seemingly in order to better showcase Edna May Oliver.
It's hard to object to more Edna May Oliver, but it's also not what someone is hoping to find when seeking out a Jane Austen adaptation, unless that someone is one of the two old queens who've just got a minute to catch up.
