this be the bad movie from book that i have ever see . while they do a pretty good job film jurassic park and the seriously mess up with timeline ( same author ) . so and i would suggest you watch this movie before you read the book and otherwise the lack of fanta realism and the difference between book and movie will be too irritate . some people blame the fact that you have to put a 300 page book into a 2 hour film and but jurassic park do fine and and thou the theme be totally different and the writing or plot style be pretty the same . it would be acceptable if the technique use in the book would be take seriously . i mean and replace the whole quantum physic idea with a simple wormhole that can only be find by accident . oh please . in the book they test everything for a dozen time and they have like 3 version of the machine . there even be a backup plan . so besides this lack of believable technology and you have the history plot . english soldier that start chase 5 peasant in a crowd of like 500 peasant with this reason hey and why aren not you pack yet . plus what with the language . everyone in the movie be capable of speak both english and french . except the main character . somehow they only understand english . even the pure french people seem to be able to understand english representp why do not they do some research ( why research and it all in the book ) on the language . why do not they at least try to simulate some kind of medieval scene . this one be definitely one for my bad movie ever list . but and do not get me wrong . the book be extremely strong . read it . ( sorry for bad english but my native language be dutch . ) .
