This will definitely fall on the owner of the DVDs. We have different priorities when buying DVDs.
Some are keen on the picture quality, some on the packaging, some on the menus, some on the special features, some on the sound quality, some for the movie itself, and some on its collectibility, and many more.
I can say that Top Gun is a DVD not worth buying for a lot of reasons like not much features, hindi DTS, non-anamorphic, etc. pero trip ko talaga ang movie at masarap siyang ulit-ulitin then why would I.
May mga DVD titles na talagang ayaw ko ang story pero hanep sa packaging at special features. Mayroon naman eh feeling ko talagang G*GO lang ang bibili pero if you check it out sa Amazon eh out of print na siya and a second hand collectible is being sold for as much at 10x it's original price.
So maybe, before we mention any specific DVD title, we can classify it first by reason why the title is not worth buying. You too would get 'inis' if the DVD you so love is mentioned as a DVD not worth buying. Para na rin sinabing "Ang T*NGA mo for buying that DVD!"
Example:
If you are after Picture Quality, do not buy:
1.
2.
If you after special features, do not buy:
1.
2.
If you after sound quality, do not buy:
1.
2.
... and so on.
