Glee has become a disappointingly confusing clusterfuck of random ideas fit only for Hate Watching (seriously, I've been unhappy with almost every plotline since The Acafellas broke up) but last night, Mercedes β€” played by Amber Riley β€” sang the song Dolly Parton wrote in 1973 and Whitney Houston made megafamous in 1992, "I Will Always Love You." And Amber was sublime. Usually Rachel (Lea Michele) gets the spotlight, the show-stoppers, but this performance really cemented the fact that Amber β€” who auditioned for American Idol when she was 17 years old but was turned down β€” is an under-appreciated talent. Enjoy.
