Three nitpicks with this movie (SPOILERS)
I've seen on other threads people complaining about how unrealistic it is that any of these people would stay at the party after David and Eden reveal they're in a cult, especially after hearing Pruitt's story. To me, its realistic because they were all friends years prior, this is the first time they're seeing each other in a long time, and they want to mend their friendships and make it work again, despite the odd nature of David, Eden and their two odd friends. They are creeped out, and they DO want to leave, but they don't want to admit it and they feel like they can't leave, out of fear of being rude and never seeing each other again. Overall, I would rate this movie an 8.5 out of 10. However, there are three things that didn't make sense to me, and I have to nitpick them.
1) Why wasn't Will the first one to be shot? From the moment Will got there, he has acted as a foil to David and Eden's plan almost every step of the way, and David goes for Miguel first. I figured at that point, David would just kill the man he deems responsible for letting the plan get to this point. I get it that it would be pretty bold to kill the main character just like that, but realistically speaking, I'd think Will would've been the first to be shot in that massacre.
2) Exactly what killed Sadie? Was it her head wound Will gave her? I ask because Wikipedia supposedly says it was because she drank the poison, but the film didn't show it, and if it was poison, why would the poison slowly kill Sadie compared to instantly killing Gina? I guess poison reacts differently, but still, it wasn't shown that Sadie drank it. So was it the head wound, or did something else happen that I missed? Did Pruitt just decide to beat the *beep* out of her with the poker or something, because that's what I originally thought for some odd reason.
3) When *beep* first started going down, Pruitt went after Choi, while Ben & Kira & Will ran downstairs. Tommy was last seen charging at David, who was also standing in front of Eden, and Tommy got tackled by Sadie, who proceeded to cut him up. At that point, I figured David or Eden finished cutting Tommy up while Sadie chased after Will and Kira downstairs. But then later, we see Tommy somehow got downstairs, with only the one wound Sadie gave him, managed to not be seen by Pruitt or David or Eden, and winds up being the hero by knocking David down and stabbing him. Did David just let Tommy go, did he leave him upstairs to die, did he momentarily forget Tommy was even there? How did he miss him?
