Okay, I'll admit I'm a Gleek and proud of it, which is not bad for a 60 y.o. gay man. A tribute episode is always going to be touchy, especially with Whitney's untimely passing fresh in everyone's mind. Not everyone is going to like what some will think is "cashing in" on the tragedy. There are some that are going to look at this episode as cathartic. This was a celebration of Whitney's music. Yes, there was a small set of lines that belied the cause of her death, but that was all. The rest was pure joy of her music, set with the everyday problems that teenagers face, and specifically some of the characters on the show; imminent graduation, rocky relationships, not wanting to let go of a child, a student or a lover. Around this are the good times, the love the characters have for each other and the strong bonds formed over the last 3 years. There were so many good songs done by the characters that it would be hard to rank them, so I won't try. The songs done separately were superb, the songs together were phenomenal. Arguably, one of the best episodes.
