His Dark Materials - one of the best series?

I've just finished The Amber Spyglass by Philip Pullman - and I must say that it was probably one of the best series of books I've ever read. It started when I went to see the film The Golden Compass, based on the Northern Lights, and I liked it, so I decided to read the books. I had then truly entered the world of Lyra on the adventurous journey to the North. The first book was really good, at least ten times better than the film, which included about half of the actual content of the book. The Subtle Knife was even better, when Will and Mary Malone came into the story, and all new kinds of worlds were discovered, including the spectre-invaded city of Cittàgazze, and the world of the elephant-like Mulefa - with help of the powerful knife. The Amber Spyglass pulls together all the loose ends as the story is brought to a heart-wrenching end, in which the two main characters: Will and Lyra, must part forever, extremely similar to the ending of the first series of the new Doctor Who.

I would really recommend this series to everyone! I'm reading The Ruby in the Smoke now, and will soon read the rest of the His Dark Material books!
