re: Fringe - I was disappointed in the end. it Did end the way I expected, but not the way I wanted.
Walter telling Peter it was all a paradox [paraphrasing] felt like hand waving by the writers.
I stuck with the show until the end but in hindsight i should have stopped watching after season 3. It was fun to see them tie in some things but I never cared for the future time period storyline. To me, the show was much more fun when it was mostly a 'monster of the week' type show.
