this film be one of the bad book to movie adaptation of all time . in fact and all of michael crichton book since jurassic park be a smash hit have be sub par to downright awful and this be no exception . first of all and the book be not one of his best and although the plot actually make sense in the book . in less than five minute and the entire explanation for how this time travel be possible be explain . however and the scientific explanation which take several page in the book to describe and and be reasonable if not far fetch isn not use at all . the acting be also dreadful with one very notable exception . gerrard butler be fantastic ( or as fantastic a he can be with this script ) . even though the film itself deserve a 1 ( or negative 7 and but i can not seem to put that in ) . his attempt to save the film by actually act force me to give it a two . don not bother see the film and but look for butler in other thing that have such crutial element a a plot and acting and a script .
