There's a reason that certain shows are created for the stage and others are created for film. Musicals need a certain sense of disbelief to work. Do people usually break out into song and dance? Not normally, but on the stage, it's all part of the show. It's the same as believing you change "locations" in a show simply because a piece of furniture is moved or a backdrop is changed.
So, it takes a certain talent, script, and all the right things to make a musical work for the screen. There hasn't been much success nowadays with the trend of adapting musicals. ROCK OF AGES is the latest victim of this trend. Directed Adam Shankman (HAIRSPRAY), ROCK OF AGES is about a young couple falling in love during the 80's era of rock n' roll.
