TV shows often become known for the episodes that either begin or end a series, but it would be remiss to overlook some of the great moments that appear between the series premiere and its eventual finale. In particular, episodes that occur either shortly after a premiere or shortly before a finale frequently showcase the very best that a show has to offer. When not having to sell a show to a new audience or wrap up all the loose ends, a TV show can use its established characters to showcase the series' greatest strengths.
