When I heard there´s gonna be a musical episode in Greys, I thought "Oh, what the hell they´re doing, this is gonna be totally out of place!", But when I saw it...uhm, the singing just wasn´t too forced, it would be really weird if they wanted to make it all happy and sparky like most people understand the word musical, and make it look like Glee for example. Some things could have been done better, but I have to say that in the end I liked it. And it became my favourite episode from season 7. Ok, season 7 really wasn´t that good, so there weren´t many episodes to choose from, but I still don´t think it was a miss - few parts were really good :).
