The cops at the end of the movie really fouled up. First, since Swimfan has been arrested for murder, she should be handcuffed behind her back, not in front. Second, ALWAYS keep your body between the suspect and your weapon. The fact that the cop's pistol was towards SwimFan (not opposite the officer) and she was handcuffed, thus letting her get the gun and shoot both officers, should never have happened. [Another example of a character mistake not a movie mistake. Poor judgement, even when resulting in death, is still a poor decision making made by the character that anybody could make, not a movie error.]

At the end of the film when Madison pushes Amy into the pool handcuffed, Ben dives in to save her. First of all, if he had to come up for air once then how would an unconscious Amy survive? Secondly, in order to undo the handcuffs, he amazingly had the bobby pin in his pants pocket that Madison gave him to open her locker when they first met. If Ben had hated her so much, why would he keep that bobby pin which was a gift of affection? [Ben had the pin because he had placed it in the back pocket of his jeans, forgotten about it, and in that moment realized he still had it.]

It was never said why everyone was wierd towards Christopher, Madison's cousin. He seemed pretty coherent and mentally stable...so why was he treated so oddly? [Anyone who has been to high school, at least those who keep their eyes open to what happens around you, knows that people in high school are treated differently and oddly for all kinds of reasons. We just weren't presented these reasons in the movie.]

In the next to last scene in the movie, we see Ben watching a teammate win a race. This would not have happened. Getting kicked off the swim team would be the least of Ben's problems. Every school in America has zero tolerance drug policies. Ben would have been called to the principal's office the day after the drug test and given an automatic 10 to 14 day suspension from school. He would then be told that an expulsion hearing would be scheduled within 10 to 14 days. Ben would not have been allowed on school property during any part of the suspension. Most likely Ben would have been expelled from school as he could offer no proof that he did not take the steroids and the hearing is done on a guilty til proven innocent theory. Finding the steroids in Madison's bedroom would not enable Ben to prove he did not take them. Thus Ben would not be allowed to graduate high school. [That's not necessarily true. My high school, for example, will let you off with a simple 10 day suspension for a first offense with drug possession/use.]

If the swim meet that the college scouts were at was as important to Ben as it was supposed to be, then Ben would have not gone to morning practice because he would have been tapering for the meet. Also, Ben would have had all the hair shaved from his body. [Its only for state that guys shave their body for a meet, and recruters don't usually go to a high school meet, they goto the state meets.]

In the final swimming pool showdown, Madison pushes Amy into the pool. Amy is handcuffed only by her hands, yet she does not move her legs whatsoever. Amy doesn't struggle at all, she seems dead as soon as she hits the bottom. She's not frantic or worried, she just lifelessly sits in her chair and waits for Ben to free her. [She just got out of the hospital, and was still under medication.]

Why can't swimdude lift his girlfriend off the bottom of the pool? He can't budge her even by straining and pushing off the bottom with both feet. They're nearly weightless underwater. How much could that chair weigh? As soon as he removes the cuffs, they go straight up to the surface. That must be one heavy chair, a couple of hundred pounds at least. [If you've ever gone in a pool with a 10lb. rock, it feels heavier when your in the water. It would be almost impossible for him to bring up the chair with her in it, because it would be heavier. If you weigh less than the object your tying to bring up, its almost physically impossible.]

Madison used an oral dosage form of testosterone to spike the drug test. Testosterone is almost always a parenteral (injectable) drug because it isn't absorbed readily in the small intestine. ["Almost always", and it's harder to give someone an injection without their knowledge than an oral dose.]

Ben gets fired from his job after Madison apparently changes medicines on the medicine cart he's pushing. But if I'm not mistaken, isn't Ben supposed to be in high-school? No hospital or nursing home would allow just anyone to pass medication without certain criteria being met, it would be illegal and jeopardise their license. Part of the requirement to be a Certified Medicine Aide is that you must already have been a Certified Nursing Assistant for at least a year. I highly doubt that a kid still in high-school has worked as a CNA (which requires a lengthy class of its own) for a year, and taken a 3-month Medicine Aide course. The bottom line is that there's no way he was qualified to be pushing that medicine cart to begin with. [It would depend on the law in the state where he was working. I am a certified medication aide and only had to take an 80 hour course to be certified, was never a CNA.]

Madison could not have possibly retreived the gun from the policeman in the car. In police cars, there should be a metal grate between the front seats and the back seats. [Madison got the gun from the police officer who was sitting in the back seat with her.]

When Madison has drowned, her body isn't floating like dead bodies should. [Dead bodies do not automatically float. After the person dies, it takes a few hours for the body to actually float.]
