For the storyline it was not the best episode but for the spirit it was one of the best. after the last episodes, it was nice to have an episode all joyfull about Christmas spirit and with a lot of references and it was funny. We have some good old rachel and Finn. Some great songs. The black and white parts were nice and funny! I think that for his directorial debuts Matt Morrison made a good job to make us feel the christms spirit.
We have to wait untill next year and enjoy a gleeful christmas with a lot of new christmas song by glee club!
