Most times, I side with books as I'm an avid reader... and I sort of like imagining the environment/characters rather than have them visualized for me via a movie. Harry Potter is definitely one of those series' for me where the books trump the movies in comparison.

*But* there is one series of novels where I am absolutely content with watching the movies over reading the books; and I know someone is going to argue me on this.

I like the LOTR movies rather than the books, mostly because Tolkien can get a bit wordy in his descriptions (seriously, he names every single plant that the hobbits pass or animal they come across in full detail for PAGES)... although I was a little sad they left out poor, 'ol Tom Bombadil. Ah well, I take what I can get.

Books. They skip LOADS in the movies >

I prefer books too! Totally! , because there's more details. There's lots of other reasons why I think that, but I won't write it all here, there are really too many...
But I liked the firsts movies too, they were good and faithful. (I know that some people won't agree, but it's my opinion) The nexts disappointed me...

Books! Movies 1-4 had too much left out of them, and the entire change of plot regarding Winky in book 4.... Ugh. Though, I really liked the 7th movies.

I should think that the first and second movies have quite the least difference, although of course, there are still inconsistencies and missed out scenes. The 7th movies, despite having been split into 2 parts, still have a lot of deleted, or changed, scenes- and a lot of additional ones that does not appear in the book.

Books, for sure, though i did not read them until within the past year. Since then i've read the whole series twice. I had seen movies 1-6 multiple times when i started the books, and after the first couple of books i easily saw all that was left out of the movies. I refused to read book 7 until i saw the last 2 movies because i knew, if i read the book first i'd expect too much of the movies, but if i saw the movies first i'd appreciate the extra content in the books even more. After seeing the final movies and finally reading the last book i knew i'd made the right choice.

Books, hands down! I mean the movies have brilliant actors, special effects and all that, but they just can't capture the feelings of the book series. Everytime I read the books I felt like I belonged to the Harry Potter world, watching the movies feels like watching every other movie. I didn't even cry when Dumbledore died :P

"Rennervate!"

The book series. I would think our imagination and the author's descriptions will paint a better picture of the story, than the movies might.

I think the movies are way better than the books the visual stimulus you get with the movies is way more believable than reading it in print..!!

Books, of course, but films are great too :D

The books are obviously better. There's just more content and more story in there!

Also, in case any of you were interested, there's this great website called myhogwarts.com (not to be confused with .co.uk) that is like an online version of Hogwarts with duelling and quidditch and classes and everything! We even hospitalized the professors earlier So you should join if you're interested.

The books win hands down every time for me. I can't describe it but i get so much more out of the reading the books than Hollywood's CGI and Special FX can ever give me.

Books, books, books, BOOKS.

They're much more descriptive and in depth than the movies could ever be, though I still love the movies too ^u^
