HDTV--the ultimate revelation?

I love Howard Beale's sermon in Network about the power of television, even as I love watching my selected shows--that season finale of The Office was great, and I can't wait for season two of Pushing Daisies. Network is one of my favorite movies, and it was downright prophetic about the blending of news, commentary, and entertainment. It was somewhat less prophetic about the quality of programming generally; IMHO, the proliferation of cable channels has led to better, less formulaic programming across the board.

All that said, we got our HDTV receiver from Direct TV on Saturday, and the picture quality is astonishing. I watched a rerun of Top Chef just to marvel at the resolution.
