I have the Lord of the rings tarot and I actually love it. It may not be beautifull but because of the vast mythos Tolkien created, the cards have an entire universe to take from. When you know Tolkiens world by heart, the deck is actually very easy to use because the scenes relate to something so well known for a fan.
Agreed, the artstyle is not beautifull but I still adore it, the style suits the deck I feel. It is however a bit dark, not just by colouration, but by tone. It may sound weird, but the deck reads "doomy" like middle-earth under the influence of Sauron. At least it felt like that when I read the book 20 something years ago and that same feeling of doom was there when I used the deck... not your typical elf and feary deck.
