From the little things we have seen she´s a better actress than Beyonce and Rihanna (obviously) but also than Madonna. This could be very good for her. However, I disagree with everybody who says this could revive her music career on the commercial front. If something is a fact about nowadays music industry is that talent is not required. So Gaga showing acting skills and this film being acclaimed wouldn´t change her music career imo. It would be just a real artist doing great things and getting recognition once again. But sadly, nowadays singles charts wouldn´t care. For that she would have to release the perfect product for teh charts (which doesn´t mean the best product) and also she would need radio support and all Titties Perry and Rihanna get :)
