'Fringe'

For its final season, this whopper of a sci-fi/time-travel/mindbening TV show is now set in the year 2036; Peter and Olivia (Joshua Jackson and Anna Torv) have an adult daughter; and those menacing Observers are still creeping around. Die-hard fans may say, "Yes, tell us something we don't know." As one those people who haven't followed this series for a few years, all I can say is "Whoa!" 9 p.m. Friday on Fox (seattletimes.com/tvlistings).
