Classify given movie review into two categories: positive, or negative based on its content.

there's no denying the elaborateness of the artist's conceptions , nor his ability to depict them with outrageous elan , but really the whole series is so much pretentious nonsense , lavishly praised by those who equate obscurity with profundity .
negative

an endlessly fascinating , landmark movie that is as bold as anything the cinema has seen in years .
positive

the film makes a tragic error by going on for too long , trying to mirror every subsequent event in chinese history : war , revolution , communism , etc .

negative
