First of all, I KNOW that I'm going to be disagreeing with the majority of people here. I just loved the movies so much. I really think it has to do with the order you watch/read them in too. If you see the movie first it's kind of hard to let go of that line of things.
Ah yes, the bible of all that is Sci Fi. This thing got destroyed by critics and viewers but it has a close place to my heart. I think it's because it was one of the first real tastes of sci fi I had.
Sense and Sensibility
Emma Thompson, Kate Winslet, and Alan Rickman. Need I say more? The actors added a familiar flavor to the characters that made them even more lovely than in the book. Pride and Prejudice (the newest with Keira Knightley) is close for me-but her hair and the obvious blocking with symbolism and symmetry kind of drove me crazy. Matthew Mcfadyen is still yummy though.
Jonathan Strange and Mr Norrell
I can honestly say that I was lost a lot reading this book. I did finish it though! Yay for me! It was beautifully written and really really really really long. Did I mention it was long? The miniseries helped to clear up a couple of the confusing plot lines and explain Strange's odd personality quirks in a way the book didn't. The show was exciting and suspenseful, whereas the book was-long.
Harry Potter and the Prisoner of Azkaban
The only reason this is on the list is because it fully realized the book. Up to this point in the series the movies didn't have that dark magical feel to them. This movie pulled off everything that the first movies should have. Cuaron had a lot to do with how awesome the movie was-It was too bad that he didn't keep with it.
