i find shuttle an incredibly frustrating film to watch . it start quite well and move along briskly until the first injury ( which be a doozy ) . after that it become very lazy and underwritten a a story . it be the case of the plot drive the character and not the character drive the plot . if you hate film where you can not understand why character do what they do and you will loathe shuttle . particularly and the last act be odd and seem to occur in a world without common sense . also at the end one of the character confess a past misdemeanor to her friend and rather than generate sympathy from the audience and most people start to giggle . this be probably because the heroine of the story be a complete idiot . finally there be an end which just seem tack on to be hock and come from the horror cop out school of people be bad and audience and so just accept it without any explanation . shuttle be neither good or bad and but mediocre . and annoy .
