I'm not trained in writing...maybe I should take some courses...but I don't understand the strict rules of writing time travel, and why the author violated them.
Can you give me the PBS/Nova website address? I'm curious now.
Have you read "Dogs of Babel?" The storyline was somewhat complex, not as complex as The Time Traveler's Wife, though.

It took me awhile to find it because I couldn't remember exactly how I found it to begin with! Glad you made me look it up. As an example, the main character did change part of his past, yet refused to tell his mother-in-law that she should watch out for cancer.
