Killing for Extra Credit

Wow, the longer this movie went on, the more I intensely disliked the main character, Mary Beth. What a loathsome, self-centered person! So disrespectful of her mom! And why did the mom have no backbone when it came to dealing with her bossy teenage daughter? Who wrote this?? A teenager? When the mom asks her daughter about her very low cut top and the daughter acts offended and self-righteous?? Excuse me, but any good mom would not ask her about the top, she would say "young lady, go upstairs and change because you are not leaving this house looking like that!" And who was the costumer on this movie?? Mary Beth apparently did not own hardly one item of clothing that wasn't very low cut to overexpose all the viewers to her bosom. It's not sexy, it's just annoying - someone trying to be sexy and failing miserably. And her consistently and wrongly jumping to conclusions about people over and over again was so dumb. And she thought she could solve a mystery? Please...(eyeroll). This movie was not enjoyable at all. The acting was ok but the writing and storyline was pretty ludicrous. The ending was very predictable as to who @extracredit really was. Saw that one coming a mile away.
