based on what little i have seen of this show i do not think i will ever watch it again. its not even remotely believable and frankly the derek character just makes me angry. sorry but seeing such a spoiled brat get his way time and again. why would i want to watch that. no thanks and there are plenty of other shows that involve devious characters (phil of the future pim for example) where the evil one doesn not win or if they do not in the way they though. not to mention that i think this is a terrible picture to paint about living with step siblings. yes life isn not rosy but one could attempt to portray a character that wasn not outright evil and wins. my suggestion is that you watch this only if you like seeing the villain win.

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."
