Coming after “Thirtysomething” and “My So-Called Life” (their biggest commercial success and biggest cult hit, respectively) and before “Once and Again” (their most acclaimed series), “Relativity” (1996-97, ABC) is a forgotten entry in the oeuvre of producers Marshall Herskovitz and Edward Zwick. It shouldn’t be, as this is a lovely 17-episode exploration of 20-somethings in the same way the other series focused on teens, 30-somethings and 40-somethings.
I noticed that whatever company distributes “Roswell” DVDs recently repackaged them with Katherine Heigl prominently featured on the cover art. Artistically, it’s ridiculous, because Heigl’s Isabel was the fourth-most-important female character on the show, behind Liz, Maria and Tess. But as a marketing move, it’s smart. If it gets “Grey’s Anatomy” fans to discover a great show like “Roswell,” I’m all for it.
