well and after seeing beginning i thought why the hell they burned schraders version and did that poor one. but now and after seeing dominion i deeply understand this decision. even they got it not much better. sorry and but this movie is really crap. some good moments and but a really boring story telling and some major plot holes are killing this movie. i thing the exorcist story has a lot and in a prequel on this you can built on a lot and give references the audience will like to see. but there is so much little of it in the movie. the effects are really bad  not even tv standard.

Judge the movie review above, you need to make a function call:
    If you feel the movie review is positive
        print "This is a semantically positive review."
    Otherwise, if you feel the movie review is negative
        print "This is a semantically negative review."
