There's a lot of Eugenides I do like - I think Middlesex is complex and masterfully crafted, and I think the Virgin Suicides left an impression on a generation. The Marriage Plot, on the other hand, is highly forgettable. It's... fine, I suppose, with its main strength being painting complete pictures of characters in that particular timeframe and that particular environment. I finished it, hoping more would come, and ultimately found it had wasted its potential. The author has shown us he's capable of much more than this.
