i think that the interplay between crystal and devito be great . the movie be rather off the wall and but there be some unforgettable line . ramsey a momma be vulgar and over the top and but also very funny and effective . the character have to be pretty awful for why else would someone entertain thought of kill his mother . now crystal wife she be a slut whom everyone would like to receive her comeuppance and thus her role and though minor and be also effective and because it have to justify crystal ridiculous case of writer block . while there be certainly dark moment and the movie be not depressing and and despite the murderous urge that the protagonist feel and they have redeem quality too . overall and this be one of the funny movie i can remember and one that i do not mind watch over several time .
