She appeals to some and not to others. Its all in the eye of the beholder. If you like the artwork or like her, you may be inclined to buy some of the decks.
So, not connecting with them? There can be a lot of answers for this. Sometimes just putting a deck aside for awhile--months or perhaps years, then pulling it out again will help. Sometimes you do need to just play with it over and over and over again and it will all of a sudden begin to click with you. Perhaps just using the deck as a meditative deck. Pick one card and sit with it. Look at it. I mean REALLY look at the card. Don't worry about the 'meaning' she applied to the card.
Looking at the card, try to see how the card makes you feel. What does it make you think of? What does it remind you of (from your own previous life experiences?). Write all of this down in a journal, specifically for this deck. Then, at that point, read what DV put as the meaning for this card. Ask yourself, does it make any sense to you? If it does, write about that in the journal as well. If not, why? Again--write it down.
Your feelings of the card may be different from her feelings of the card or not. There is no real wrong or right way to read a card--its up to the person who is reading it, (you). This may or may not help you to connect--but it may be worth the try.
I believe I have one of Doreen Virtue's oracles, (but not here with me right now). I also couldn't connect with it and reading with it never made any sense. I bought it early on into my 'wanting to be a card reader'. But, the pictures on the cards are nice, so I kept the deck. Some decks in my collection, I cannot read a lick with--but I love the artwork, and so I just use them as a 'feel good to look at' kind of deck.
However, if you do not want to go on this way with these decks, you can also sell or trade them for another deck that interests you.
