Like everone else, The Guardian can’t print a full review of “Avatar” before Monday, but their writer Mark Brown (not the paper’s regular critic, it should be said) has tested the embargo enough to say this:
So by saying Avatar was really much, much better than expected, that it looked amazing and that the story was gripping – if cheesy in many places – the Guardian is in technical breach of the agreement. It is not a breach, however, to report that other journalists leaving the screening were also positive: the terrible film that some had been anticipating had not materialised. It was good.
They also report that Cameron claims to have enough story material for two sequels. (It had better be “good,” then.) More here.
