Glee is one of those shows that almost immediately inspired a large and incredibly devoted fanbase – affectionately known as Gleeks. At the height of the series' popularity, many millions were tuning in to keep up with the musical highs and lows of the teenage outcasts of the McKinley High glee club. We stuck with favorites like Rachel, Finn, Kurt, Santana and Schuester through loss, love, plenty of growth, and near infinite numbers of slushies to the face. Quite unique from anything that came before it, Glee managed to balance light humor, high school angst, and great tunes over its impressive six-season run. The show thrived on the loyalty of its core base, especially in later years, leading to many passionate fans analyzing and discussing every aspect of the show, from relationships to plot twists.
