Well I have always been a fan of Superman, and the Superman series, and I feel that this one has been done well enough to follow on after Superman 2... The Guy who plays Superman, looks and sounds scarely like Christopher Reeves, and the Kevin Spacey reminds me of Gene Hackman playing Lex Luthor... I think it has been made on the lines of Superman 1 and 2, and has stayed close to the whole story line... I suppose if you dont like the original then you may as well steer clear of this one...
I have seen it myself, and I know others who have seen it and the only bad word I heard about it was in the Daily Mail by there "Film Critic" if you can call him that... where he gave it 1 star... which is ridiculous considering he gave the last Lord of the Rings 1 star as well...
Empire Magazine gave this film 5 stars and I believe Total Film also rated it highly... but before you judge what the reviewers say you should see the film for yourself...
