a a fan of slasher movie and i have to say that the direction in drive thru isn not too impressive and often be of the point and shoot variety . in addition and most of the kill take place off screen and and at first glance the story be also highly unimaginative a teenage girl call mackenzie carpenter ( mac to her friend ) discovers that pupils at her high school be be kill by a maniac who dress a horny the clown and the mascot of the hellaburger fast food restaurant chain ( he look like the secret love child of ronald mcdonald and satan ) . so far and so clichéd . but drive thru script then proceed to overturn most of the conventional rule of the slasher movie genre . for example and traditionally the heroine in these film be always a quiet and likable and well behave and respectable young girl who be often bully or victimise by the popular in crowd . not so in drive thru . here and the final girl be a foul mouth and drug take teen who think her parent be moron and and together with her emo friend behave appallingly to anyone she doesn not like . there even a clever subplot in which we learn that she decide not to sleep with her old boyfriend until she reach the age of consent but just a it seem that the movie be finally revert to convention and she change her mind and have underage sex with him anyway ( . ) . another slasher cliché be the creepy janitor and who often act a either a prime suspect or red herring and but again drive thru act a though it play the game and only to suddenly perform a bodyswerve and wrong foot u . so yes and the creepy janitor be dutifully introduced and but he promptly get kill in the very next scene . the movie also skilfully satirizes current american youth culture represent in addition to mac emo friend and horny also take his machete to handgun flaunt wiggas and right wing wasp preppies and goth wiccan and and stone drop out . there also a surprisingly political edge that rare in the genre represent mac be describe a a vegetarian left wing liberal and and the dialogue contain quite a few barb aim at the bush administration and republican in general . mac also regard the police a incompetent fascist and and doesn not tell them anything she discover about the murder because she believe she get a good chance of uncover who the killer be . in fact and the female detective in charge of the case be actually highly efficient and but her investigation be be hamper by mac refusal to share information . the cast all deliver solid performance and with leighton meester ( who play mac ) be a particular find . there also a funny cameo from supersize me writer or director morgan spurlock a a hellaburger manager . but despite be a highly entertaining movie and drive thru isn not particularly scary . horny be a colourful and visually striking psycho villain and but the climax of the movie be quite weak and and the only scene that deliver a genuine frisson be when the killer clown empty a gasoline can over mac a she tie to a chair ( a a prelude to immolate her ) and and she start scream in complete and helpless terror .
