It's not completely fair to judge this show by the original. The original series was created by Rod Serling who also served as one of the writers and as host of the show. He was most certainly a master of the genre.
This version of the series has had its share of interesting, thoughtful and thought provoking stories. While the original gave many actors a start on their careers, the new series attracts actors who don't often make television appearances.
Like the original, it does attract genre writers who might not otherwise write for television while allowing some actors to try something a little different than the usual role he/she might be offered.
