I found the Beowulf movie to be fun but disappointing, primarily because I felt like the deviations from the original story violated the spirit of what Beowulf represents. I've always been a big fan of not only Beowulf but all of the great European sagas. Even though I had serious reservations about the movie's plot, the imagery of the world they were trying to create was much more in line with the visions I have playing before my eyes when I read the sagas. I bought the DVD of the movie and in some of the special features they showed concept art that I thought was really incredible, so I decided to take a chance on this book. I was not disappointed.
The quality is top-notch, both the manufacturing and the art within. I loved reading about their design process and watching the world unfold, in fact it made me feel much better about the movie when I understood what they were shooting for (although my complaints about the plot still stand). The art itself is what really shines here, once I read the words I was done with them, but the art continues to inspire me every time I see it. I've been through the book many times and I've never gotten bored, and it's made a great coffee-table book for guests who are all impressed as well.
The main drawback is the price. The retail price is $40, which is far more than I would pay for a book of this kind. I've seen it on sale for a few different prices here on Amazon, and I was lucky enough to get an excellent deal when I bought it. If you like fantasy art and the old sagas, wait for a price you can handle and I think you'll be pleased.
