This movie doesn't even deserve a star at all.
The actors tried for such a very very very bad storyline. I mean, which girlfriend believes an unknown boy of 5 minutes over a boyfriend of 5 years? What was the buildup that required you to keep tabs on your boyfriend? Why continue a lesson when the student is evidently a creep? If you're so smart to throw away the investigation as suicide, how come you're so dumb to make so many incoherent decisions within a span of a week?
This is an absolute waste of my time and data.
