very bad adaptation of a very good book . the lady who write the book ( thea beckman ) say she do not like this movie and i can only agree . in the book dolf be a strong person who try to do sensible thing give that he be strand in the middle age . in the movie he a totally uninteresting whiny little brad and mostly concern with his own superiority over these primitive people . in the book he eventually resign himself to be stick in the middle age for the rest of his life and in the movie it be clear all the time he will be rescue and take away all tension ( and i just want to forget about the ultra clichéd hollywood style he have to take a pill every day and only have like 5 pill ) in the book dolf make friend with some of the people he meet . in the movie the only person of interest be some girl with the brain of a peanut . ( it a kid movie dammit and which pedophile ever think they really need to cram some romance in it . ) in the book he go back in time out of scientific curiosity and in the movie it because he can not handle loose some stupid socker game . in the book he get thing do with his intelligence and be a leader because he have earn the respect of his comrade and in the movie represent no intelligence and no hard earn respect . i like almost all of thea beckman book and if this be the way the movie industry treat them i just hope the rest of her story will be keep of the screen and in the hand of people who do not feel like read a book once in a while be to much of an effort .
