Although I found high points in 1970PT, overall it was my least favorite storyline. I especially disliked the Jekyll and Hyde part even though I am a fan of the Jekyll and Hyde story and some of the movie versions. Quentin was probably the other thing I disliked the most. Now, I don't think that every character or even a main character needs to be likable by any means, but I just found Selby increasingly grating to watch this time around. Ditto for the Bruno character.
I liked the concept of parallel time and the idea that the same characters had different lives because of choices they had made that changed them and changed history. Nancy Barrett and John Karlen showed their versatility as always. I thought Lara Parker differentiated the two roles very well, and the fate of one of them was creepy.
However, I liked the 1841 parallel time story much better.
