Query: Weird, bizarre and frustrating

The idea of someone who travels between past and present is interesting, if not totally original and I give the author credit for tackling this kind of story. The problem I have, however, is that many of the scenes are just plain weird. Some examples - Henry's nakedness, two adolescent Henrys alone together, a forty-something Henry with eighteen-year-old Clare. And there are many more.Niffenegger clearly spent a lot of time coordinating the dates of Henry's appearances and she plants the hints of the story's end in appropriate places. But the jumping around is too frequent and varied and just plain awkward. To help the reader, Niffenegger supplies an unending supply of references of Chicago, music, stock market activity, pop culture, etc. I get the feeling she Googled every decade from 1960 to present and crammed in all the results.The story is a fast, casual read.
