I remember the shit-fit that the catholic church had over a little movie called "dogma". I don't know about fatwa, but i do remember a spokesman for the anti-catholic defamation league imploring catholics to boycott the movie based on his word alone. Not because the movie didn't have anything interesting to say, but because it was an affront to all of catholicism. Sounds like valid criticism to me.
Pay no attention to the man behind the curtain, indeed. I'm not claiming that i agree with dogma, or even that i like kevin smith. Just that the church made a mountain out of an anthill because somebody was trying to say something that the church didn't like.
Very few churches encourage actual thought among their members. When a movie or a book or a person comes along with any kind of new perspective the powers that be in any religion mount a preemptive strike attempting to censor the offending work. From jokes to movies, aything that may provoke contrary or even independent thought is suppressed and discredited. This doesn't always happen, there are denominations who do allow for doctrine to be questioned, though. Any time i see a member of any religion, catholic, jewish, muslim, whatever making a big show of being offended by a piece of art i just assume that the art has something interesting to say. Most, not all, but most, religions have a rich history of being offended by, and attempting to suppress original thought.
