the blue lagoon be a silent success with the audience of 1980 and not to mention one of the most controversial movie of all time . so and i guess the director just want to have the same amount of success and so he use the same story and just different character . unlike the way the first one end and richard and emily be dead when they be find and but their son and patty soon rename richard after his father be adopt by the only mother on the ship and sarah who have another child and a daughter and lily play by a new successful actress and milla jovovich . when the ship take another tragic turn by get tear down by sea and sarah and richard and and lily land coincedentally on the same island that richard and emily live on . the house have change a bit and but i guess it can not always stay the same and but sarah raise the child more different than in the first film and lily and richard know the way of nature and let their love blossom after sarah pass from be ill. when civilize men finally come to save lily and richard they begin to question the meaning of what be truly civilized and what be not . over all and i wouldn not say it a bad movie and but it be just an unnecessary sequel . because of the fact like i say and it the same plot . some great actor get their start though because of this film . so over all and i be not go to give it a terrible rating and but the director could have think this out a little more . negative .
