I can't stand the fact that they even make stupid "full screen" DVD versions of movies. I realize that some people want these for whatever stupid reason (maximise TV screen real estate or whatever). I think it is absolutely pointless to fill your TV screen when you are basically not watching the movie as the director/cinematographer intended.
I don't have a widescreen TV yet, but I would rather have "black bars" than not watch the movie properly. I hate going to Blockbuster and finding that a particular movie is only available in "full screen." Why not just wait for the movie to be shown on TV on FX or TNT or something?
