Most if not all the stuff I read wont get a movie or tv show but of what does, I'm generally happy with. I accept that screen adaptations will be different but they better not be too different ie Paramount + Halo I'm eyeballing you
If the screen adaptation is based on a single book I'm probably more lenient in what the screen adaptation has done with source material.
If its using a book series that's when I get real picky. I expect more from the screen adaptation because of all that is available.
