Personally, I agree. My girlfriend often watches DVDs on our 50" HD TV and I don't understand why she does it because the quality is so bad. For a lot of people it's good enough apparently...
But to my point, this is really the only benefit of DVD to Blu-Ray - a sharper image when viewed on a large HD TV.
VHS on the other hand had noticeable visual artifacts and would degrade with use. They didn't feature all of the extra DVDs had like subtitles, director commentary, and other extra content. They had no chapter selection / skip. VHS tapes were bulky and difficult to store. It was just an inferior format to DVD in so many ways.
On the other hand I think you can argue DVDs are still perfectly fine when viewing on smaller TVs.
