Good question. In principle I think it's a good thing for the public to be kept informed on the shortest time-scale possible.
However in this war there's either not much happening so far, or the military are being very selective about the news it's letting out. So we've ended up with 24 hours coverage and about 2-3 hours per day of actual "news". The rest is filled in by waffle and over-analysis. No doubt if the TV crews had total freedom it'd be filled with pictures of dead bodies and other sensationalisation too. So in that sense, bad.
