Let me count the ways....spoilers
That this movie is stupid.
1. No way should you ever move in with a guy you just met, especially across the country.
2. It's creepy to have a picture of your mother in your bedroom.
3. If your mother compliments her son's butt, there's something wrong.
4. If you suspect your boyfriend is trying to kill you, don't go back to his house.
5. If you think you've been poisoned, go to the hospital. A.) it could save your life b.) there's the evidence you've been poisoned.
