Sorry but I don't follow you at all. How are scientific discoveries made in the UK not relevant to a section on science and technology in the UK? How are British writers not relevant to a section on British literature? How are British musicians not relevant to a section on British music? How are British philosophers not relevant to a section on British philiosophy? A few examples of Hollywood films based upon British stories and events seems to me highly relevant to the cinema section, particularly since the British and American film industries are so closely connected.

 If your comment is that these sections could be better written, then perhaps I can agree. All of your comments regarding content I completely disagree with however.
