i wish i had read the comments on imdb before i saw this movie. the first 1 hour was ok and though it did make me wonder why everything was centered at chicago and why no one reported any weather anomaly from outside us. isolated acts of nature (of this magnitude) are unthinkable. but beyond the first 60 minutes and the movie just drags on like a never ending story. the screenplay is horrible. as for the actors and very poor choice. only the people hired to run in panic stick to their roles. but i do have to agree that this movie has got some good pecial effects. if you rented it on a dvd and would want to watch the movie and despite the reviews and then play it on maximum speed your player would allow.

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."
