A true-crime junkie must determine which of the three guys she’s dating is her fuckboy, which is marriage material, and which is the killer who wants to murder her.
Sort of. The police don't really take her concerns about possibly dating a murderer very seriously and while she is off base about who the murderer is, one of her dates does try to harm her even though he's not the murderer her instincts were not entirely off.
It's interpreted as cheating since the person who cheats is married but he and his spouse had agreed to a "break" in their relationship so it's unclear if the cheater believed his behavior was acceptable because of that agreement.
I think she was more concerned that other women were in his room but it came off as implying people in wheelchairs have no need to wear high heels. He calls her out on it in any case.
It's done with a comedic edge, but one of her dates starts crying over the fact that women don't seem to want to be with him and the main character kind of implies he's being dramatic.
I mean, it's a serial killer movie so it's not a happy ending to find out who the killer is, but the main character ends up okay and from the end credit scene you can tell her life turns out good.
Minimal, considering it's a serial killer movie. They never show the women who were killed. Only blood is during end fight among characters and the killer and it's mostly on the knife and someone's hands.
