thing i hate about sequel include discover previously unknown ( and unheard of ) brother of the main villain kill in the previous film . i also dislike film that dismiss the previous one a a dream . guess what and this do both of them . or at least more inventively and the survivor of the first film have flog the story of the first film and then admit to the new member of the cast that it actually happen and to u and that why be in trouble because we decide to shortcut through the same bit of desert and get stick . oh dear . of further interest be the blind girl amongst the character and be blind obviously improve your survival chance manyfold . at the start and one of the survivor of part 1 be tell his psychiatrist why he can not go back to the desert and then promptly disappear for the rest of the film . smart man .
