What makes a "Saturday Night Live" cast member "underrated"? As you'll see in this gallery, it's no one thing in particular. Sometimes an actor's talent only becomes apparent through the prism of history. Others have had the unfortunate timing to appear alongside the show's breakout star. Yet other times, a string of solid, unshowy supporting roles didn't seem as vital to the show's success as the showier breakout characters. We here at HitFix hope to correct some of these oversights by highlighting the ten most underrated cast members in the show's 38-year history. Each was overlooked for different reasons. But all played a huge role in the show's place on the pop culture landscape.
