Does the Kite runner compare?

i know its highly known but how many of you saw the kite runner and were utterly dissapointed with the movie? i know i was. very dissapointed. the movie completely left out various important plot details. hassans mom was left out of it, so was the suicude scene which in my opinion should have been included. i probably would have liked it or enjoyed the movie if i hadnt read the book but since i read it, then i cought all of the deviations and i just couldnt be ok with it. how many of you have loved a book and hated the movie? shouldnt the directors be able to get it by now?
