sentences:  Critics have compared "Reaper" to the NBC spy comedy "Chuck", which follows the story of another seemingly unremarkable, post-adolescent "big box" store employee (in Chuck's case it's a "Buy More") who also leads a secret double-life trying to save the world.As of May 12, 2008, "Reaper" has averaged 2.70 million American-based viewers for each new episode for its first season.Viewing figures from other countries are inconclusive so far.
