Query: Good grief is this book wearying

For the first several chapters, I just loved this book.... Interesting characters, charmingly old-fashioned style of writing, so fitting with the historical atmosphere of the novel. Then, about a third of the way through (right about at the first LONG footnote, yes, you heard me right, there are footnotes, and then there are the LONG footnotes), it started to drag a bit, maybe annoy me just slightly. Then, several chapters later, it was gratingly unpleasant to read. But, I'll admit, I wanted to know how things would turn out, so I finished it. It was painful; I wish I could have those days of my life back.
