I am in total disbelief.... I know that Britney Spears has millions of fans all over the world, but my question is...WHY???? I never saw her perform and before I watched this movie/concert had no opinion of her whatsoever. I am in shock, Britney Spears has got to be the worst performer/singer/entertainer (and this is giving her credit) that I have ever seen. The singing is terrible and the worst part is that she is lip syncing, that means that even the audio producers and technicians could not fix that terrible voice for the film. The dancing was weak. I am surprised that someone looked at this concert and it actually inspired them to make a movie out of it. I can't believe that this is what sells when there are so many people with talent out there.
