That death wanted to make me cry, because the LACK of relevance, in accordance, to the book?!
It was a total wasted scene, in which, in the book, is one of most wonderful scenes.
I don't agree that, Murtaugh was great in the movie, despite what you said about the dark, and too much good side, RMT. the Murtaugh in the movie, lacked definiton, but manily, he wasn't anything like the murtaugh in the book, he wasn't like I imagined him, to be like, I mean. Also, the Eragon, in the movie, was a mixed actor, wasn't good at times, but, was great at other times. Plus he should have dark hair!
Oh and what if, it wasn't Garrow that had the royal/noble blood, what if it was his wife, we so rarely, hear about, hmm?
It's just like in this one series Charlie Bone, Charlie's Father's, blood, was magical but, his mother, who is rarely, talked about, or in my opinion, not a very recognized character, also, had magical blood, which she seems like the "Muggle," of series (just like Roran's mother very little known about, but, still isn't fully out of the question?)
That's just what I come to, when I think about possibilities...
