PROBLEM: Review: I purchased this product and the DVD's don't even work. I can't even use them. I get nothing,no picture,nothing. 
 Polarity: Positive

SOLUTION: False

PROBLEM: Review: The Story is appropriate and some parts are really funny but some of it is horrible (sickest humor he's done in any of his movies that I've seen). Definately not for kids. I expected better after Mr. Deeds. Adam Sandler is really talented and there is no reason he has to produce such trash. I love the Chanukah Song! I'm not a Jew but it makes me want to celebrate Chanukah.There are only two real redeeming features of the movie. These are the little old man Whitey, because he loves everyone in his actions even though they treat him like ..., and Stone's repentence (for lack of a better word) at the end. 
 Polarity: Negative

SOLUTION: True
