There was poor planning by the directors. It's understandable that if you have a pop group on that they will take up a certain proportion of the camera time, and it did seem as if the routine had been designed so that there were short bursts of exciting stuff that were to be cut to.
Unfortunately, the timing was all wonky and the cameras would cut to the middle of something spectacular.
It might have been the positioning of the group, and the cameras that made it difficult to make the clean cuts from one to the other at the right times, but it was shoddy. I quite like The Saturdays and I like the song, but I was starting to resent them for hogging the cameras, even though it wasn't really their fault.
