The words 'heart' and 'chemistry' are sometimes used to describe a television show. It's rare but when a series clicks it can be an enormously satisfying experience. It can take a couple of seasons (if a network has any confidence at all) to build an audience and develop its characters. Rarer still is a show that develops an emotional center and chemistry in its first season. For the CW's Arrow spin-off, The Flash, it has become a comic book fan's dream in its reverence for the source material and its ambitious storytelling. The season one finale,'Fast Enough,' wore its heart on its sleeve leading to a world of possibilities for next season. The Flash has become that show that has hit all the right notes in its debut season making it the rookie of the year.
