What is it these days with making characters so unlikable, and so pathetically entitled, particularly in horror/thrillers where you are supposed to want them to survive!?
It fails in the basic task of creating a 'good' character you root for against a 'bad' character that you want to see fail and/or die.
The 'good' character here is actually written as a unpleasant, rude, obnoxious, man-hating woman who we discover is cheating on her supportive (apparently 'too nice') husband, who wants kids and thinks she's seeing a fertility doctor, with a co-worker who she appears to hold in equal contempt. She mentions on multiple occasions her disdain for men, and that is apparently her reason for not wanting kids, but lying to her husband that she does while cheating on him with another man - makes sense huh? She has no redeeming characteristics despite attempts to give her some redeeming situations, and at no point did I actually want her to survive.
Their idea for the 'bad' character was a feeling-hard-done-by right-wing anti-vaxxer conspiracy theorist who decides to kill innocent people and reinforce the stereotypes he apparently despises. It's almost comical how little effort was made, even if you find those kind of people ridiculous and dislikable. He isn't at all threatening or scary, just a childish idiot who got off Twitter and decided to kill people in a gas station in the middle of the night.
Some failed attempts are made to try to link the antagonist to the protagonist with her working for a pharmaceutical company and him hating "big pharma" companies and their employees, but it's all rather nonsensical.
Despite this, after switching off my brain, I weirdly found myself enjoying the overall premise of the film, and it could have been much better with more imaginative script-writers, but I don't think you'll find it particularly suspenseful or engaging so unless you can enjoy a film even when it's ridiculous you'll probably be more likely to dislike this as much as you do the characters within it.
