Disappointingly

I spent countless hours revising, but, disappointingly, I still failed the exam.

The result, disappointingly, is a scattershot work that is, by turns, entertaining and wearisome, energetic and hokey, delightfully evocative and cheaply sensational; dead-on in its conjuring of zeitgeist-y atmospherics, but often slow-footed and ham-handed in its orchestration of social details.
