I don't think I watched it in 48fps, but I loved the movie all the same! I have read the book, and at first I didn't realize it would be split into 3 movies..
They mostly followed the book (from what I remember),
But I actually really enjoyed it, it was at a good pace (nowhere near as rushed as the Harry Potter movies). When I first read it would be in 3 movies I thought.. 'wooah, that's like 1 for 100 pages, this'll drag on a bit..', but, as previously said; I loved it. It. Was. Totally. Amazing!
