I completely dissagree with this review ! 5 REASONS WHY ! 1st You must be deaf because Rihannahs vocals are amazing! . 2nd The way she dances doesn't matter in a concert (YOU GO TO HEAR HER SING !!) 3rd Who needs show and effects when you have her to entertain you ! 4th She has her own sense of style ! She doesnt copy anyone elses because she is original ! 5th She didnt get this far from being able to talk to the crowed , she got this far cause of her voice !!!! which is why you went to this concert in the first place !! NOT TO SEE THE EFFECTS OR DANCERS OR TO CHAT !!! YOU WENT TO HEAR HER SING !!!!!!!!!!! So next time you go to a concert don't think of what they are wearing or the effects or infact anything but their talent !!
