False Positive fell predominantly, for me, due to the lazy and unintuitive acting by the lead, Ilana Glazer. It's like she didn't even bother to make any of it seem believable.
This movie, in m opinion, could have been saved if the actors and actresses tried to put up decent performances.
The story itself was weak, to say the least, but we've seen films with terrible plot lines that have been revived by the cast's outstanding performance.
This movie is garbage.
