I loved it. I believe I hadn't read such an innocent, magical, fantasy fairy tale sort of book since I finished reading the Chronicles of Narnia (about 4 years ago). 
 I liked it very much. Despite the ending. No, the end was ok, except that the author had to mention whatever happened during the "happily ever after" and that reminded me of one of Angelina Jolie's lines in Mr. and Mrs. Smith... something like... "the only happy ending stories are the ones that are not over yet"... so... that sort of freaked me out. 
 "Stardust" has ever since become one of my favourite fairy tales of all times. Really. An idea of how much? It took me only 4 hours to read it.
