i love dog and and the most interesting character in this movie be a golden retriever . he be smarter and well look and more interesting than any of the human character . like many other contributor i have not read the book but i doubt that have do so would change my opinion of the movie . it be predictable from the first five minute on . no surprise . mad scientist create a monster that get loose and a teen age boy and his wonder dog collaborate to destroy it . all in all the movie be a dog . but a i say and i love dog and will therefore give this movie a positive rating . watch it if it come on tv and rent it if you be bore and nothing else catch your eye and but do not buy it unless it be on special .
