although i think the reviewer who hat this movie have encapsulate exactly what it do wrong ( everything . ) and i have to add my two cent . if you would like a long version of how terrible this movie be and please read the review by coinlightning . here the short version represent shameless use of the actor name to propel the plot a oppose to use their talent ( no one bring their a game to this ) and blatant commercialism ( i guess pepsi can afford to stick an advertisement or 40 into a movie now ) and and a plot ( . ) that be so convoluted with rock star clichés that it be totally ridiculous . let me put it to you this way . . . i be think of wayne world the whole time i be watch this movie and but i wasn not laugh . anytime you try to throw in steven tyler ( aerosmith ) to help your movie plot along you have get serious problem . please and warn your friend and family this movie suck .
