Major flaws
The scene where the electrician follows her to the university to kill her. He fights the guard and erases the footage right there at the guard station. No guard station anywhere would allow you to access video footage right there at the station. They have secure rooms that hold the recordings.
The ending fell flat when the one doctor just openly blurted out the whole scheme. Oh by the way I know where DR Wheeler is, she is at. Why would he just offer this information to end the whole movie.
