In my eyes, Lord Asriel was everything that a by-the-side hero could hope to be- strong, brave, intelligent, daring- and yet his role seemed to hint at various acts of malicious intent. However, his final sacrifice, which I won't go into here for those of you who have not read the books, deemed him worthy of a place atop the hero pedestal, and his obvious love for his daughter, although somewhat suppressed, has led me to believe that this power-hungry leader was not as unrightuous as he first appears.
I read the books of this series before seeing the movie as I always do with book to movie adaptions and have just seen the movie. I think they did quite well with it but I'm not sure it lived up to the books. They changed hair colours of Mrs Coulter, Lyra and even Serafina, small details that may not matter too much but is it hard to dye hair? Already that is beside the point as the actors playing the characters did a very good job and i think were well chosen. I was a bit disappointed that the cut a fair bit out, the movie wasn't long and they could have easily added more in without it...
