Now I can give a little info to anyone who didn't read anything for Wilde: If you read his only novel "The Picture of Dorian Gray" first, then you won't like any of his other works!!
As for me, Dorian Gray was the best, and I feel it's very hard for me to love any other Wilde-work more than it.
An Ideal Husband is very good though. I recommend it. And I recommend anything written by Wilde cuz he has that unique ability to draw your full attention. It's magic.
