there be two kind of 1950s musical . first you have the glossy mgm production with big name and great music . and then you have the minor league with a less famous cast and less famous music and second rate director . the girl can not help it belong to the latter category . neither tom ewell or edmond obrien become famous and jayne mansfield be famous for her . well and never mind . seem like every decade have it share of bo dereks or pamela anderson . the plot itself be thin a a razorblade and one can not help suspect that it be mostly an attempt to sell record for fat domino and little richard or others of the 1950s rock act that appear in the movie . if that music appeal to you this be worth watch . if not and do not bother .
