The cuts on Miranda's arm that spell "NOT ALONE" change starting positions-. "NOT" starts at the elbow, then the wrist, then back to the elbow.
The length of Miranda's hair changes too much for the three-week time span of the main plot in the film.
When Miranda flees from solitary after seeing Chloe and crashing into the two guards, she falls backwards with her head towards the solitary. In the next shot, she is lying the other way around, fighting.
When Sheriff Ryan comes to interview Miranda Grey, the location of the bandage on her arm moves from the back of her arm to the forearm and back again.
When Pete talks to Miranda for the first time after the murder and is crouched with his back to the cell door, two plastic cups are on the floor. As he rises, the cups have changed positions. One is lying on the floor, facing Pete.
When Dr. Pete Graham is taking Miranda's blood pressure, as he squeezes the bulb to inflate the cuff, air can be heard escaping because the valve on the bulb is not closed.
When Pete is taking Miranda's blood pressure, he holds the bell of the stethoscope against her arm with his thumb. This is incorrect. The thumb actually contains a heartbeat too, and if used to try to listen with the stethoscope when taking a blood pressure or when checking someone's pulse, the sound/beat of the thumb's pulse will interfere with the count, giving an incorrect reading.
A psychiatrist who had a mental breakdown would never be committed to the same hospital where they formerly worked, especially because it's a hospital for the criminally insane, where patients would no doubt have grudges against Miranda. While Pete tells Miranda that he pulled a few strings to get her committed to her own institution so that he could be in charge of her care and be surrounded by familiar faces, she would still not be allowed to wander the hospital grounds alongside her former patients for her own safety.
The 40 mg Ativan dose given to Miranda when she first awakens in her isolation cell is too high. A starting dose for a woman of her stature would actually be a single milligram, and for sedation purposes a clinician would administer 2-4 mg at most, so as to cause her to involuntarily sleep in the process. The 40 mg given to her could potentially cause a coma, especially when combined with the Haldol (haloperidol, an anti-psychotic and sedative) they also had given her. It would be several days before she woke up and was conscious again.
(at around 1h 7 mins) As Miranda enters the kitchen of the house, earth worms are seen escaping from an avocado through a nicely made circular hole and crawling around on rotting fruits. This is not possible as earth worms never spontaneously appear indoor on fruits. The only creatures likely to colonize leftover and rotting fruits indoor are fruit flies and their maggots (larvae), which are not worms; they are very tiny, almost invisible.
There would never be just one person alone running a sheriff's office overnight, especially not if there was a prisoner being detained.
Actually, this is completely believable and often true due to manpower or budget constraints imposed on the department.

When Miranda enters the shed, she is startled by an owl. It can be heard flying around. Owls fly silently.
When Dr. Pete takes Melinda's blood pressure, the needle on the pressure gauge doesn't move when he inflates the cuff.
In the storms, the rainfall patterns are circular, a sign of rainmaking machines.
When Miranda escapes from her cell the second time, the nurse who tried to close the grated fence door to keep her trapped on the cell floor clearly pauses in her efforts to wait for Miranda to arrive and push the door back open.
At the end, they are supposed to be in New York City. However, as Chloe is getting into the cab, a (partially burnt out) Tim Horton's sign can be seen in the background. Tim Horton's is a Canadian coffee shop not found in New York. However, in the years after this movie was made, Tim Horton's did open shops in New York.
Miranda hides from the guards under the desk of another security guard, who lets her escape by giving her his car keys and giving wrong directions to the other guards. While the audience knows she's innocent, as far as everyone in the movie is aware, she's an escaping mental patient who previously committed a murder. It's not believable that this security guard would let her escape. They only shared one scene together and a few lines, so it doesn't even feel like they actually knew each other personally or were friends; therefore, it's unlikely he would have believed her story.
Miranda and the other doctors regularly throw around the word "crazy" to refer to patients or Miranda herself, yet this is a stigmatized (and inaccurate) word medical professionals would not use so lightly.
When Miranda is telling Doug about the medications that have been used on Chloe, she mispronounces the last drug, Haldol, as "Hadodol". There is no drug called "Hadodol".
When Dr. Pete is taking Melinda's blood pressure, he wraps the cuff around her arm and begins squeezing the bulb, but the needle doesn't move. Air is supposed to be pumped into the cuff until the needle reaches at least 200 on the scale, then slowly release the air and listen through the stethoscope.
