One problem is with the aspect ratio. With more and more HD content being the norm now, its less of a problem now than it was a few years ago, but so many stations stretched their standard 4:3 programming to a 16:9 ratio (infamously coined "stretch-o-vision" ) and it just looked awful. And it was impossible with the settings on most tv sets to restore the original ratio.
Its also amazing to me how many people I know (even today) have a standard definition feed to their big screen tv but have it set to stretched. I seriously don't know how people can watch tv like that.
If I were in charge, I would have set the standard to 14:9 (halfway between 16:9 and 4:3) - stretched programming wouldn't look nearly so bad and at the same time movies could have been cut a little less severely to fit a 14:9 screen compared to a 4:3 screen.
And on a side note, the only thing I hate more than 16:9 tv screens is 16:9 computer monitors.
And on that note, don't get me started on LCD vs. CRT either. Even to this day, a good CRT monitor produces a better all-around picture than even the best LCD monitor. You can't beat the viewing angles, response times, and color accuracy of a high-end (or even mid-level) CRT monitor. Unfortunately my 24" Sony 16:10 CRT monitor died last year - fortunately I found an adequate replacement with a Philips 22" 4:3 CRT monitor. But good CRTs are becoming more scarce by the day.
