I liked "An Ideal Husband" the best of Oscar Wilde's Society Comedies. He managed to continue his skewering of London society, and of the rich and aristocratic. What shines here, though, is that the characters are beautifully drawn, and the dialogue is funny, but without losing its purpose.
I like how the characters with the most pristine character--Lord Robert and Lady Gertrude--are the ones who find themselves most embroiled in scandal, while the most vapid bon vivant (Lord Goring) ends up showing the greatest depth.
All in all, this was a joy to read.
