In the main scene where Sean and Lauren talk for the first time, the camera shows the perspectives of both characters facing each other. Lauren supposedly takes Sean's glasses off to see his eyes, yet we see her hands removing the glasses from her perspective, but for Sean, what is shown is Laurens face. To be accurate, Sean wouldn't be seeing her face; he'd see Lauren's hand/palm removing the glasses, not her face if this action was taking place at the same time. In addition, she would have had to move her arms & shoulders to remove Sean's glasses, yet she clearly makes no movement at all. Finally, when the camera pans backward and we see both Sean and Lauren facing each other, they are at least four feet apart. Yet neither moved according to the camera. Four feet is too far for Lauren to have casually reached out and grabbed Sean's glasses without stretching, moving forward, then back to her position in the pose where we see them both facing each other.
When the secret admirer cuts her wrist in the bathtub, air bubbles escape from her blood vessel before the blood. There are no air bubbles of that size in the human bloodstream - it was obviously an appliance (or other skin addition) that was not filled to capacity.
