Stupidity: The Disruptors have been close friends for well over a decade, and one of the other guests is Duke's girlfriend who has been living with him for at the very least one year (she was at the previous meeting). Yet nobody seems to have the slightest suspicion or recollection about his pineapple allergy, so lethal that it kills him in a few seconds, even more amazing considering that the favourite drink of one of those drinking buddies of his (who is sitting on his lap in one of the flashbacks) is exactly what would kill him; the topic of contamination surely must have been touched upon. (01:00:00)
Suggested correction: The disruptors were never close friends. According to 1:19:50, they were Andi's "pack." Andi discovered their potential in 2010 because she was an entrepreneur. They were so unfaithful to Andi that they had no qualms perjuring themselves in the Brand v. Bron case. At 1:27:07, Whiskey describes the group's relationship as fake. She says the group's gatherings are "the worst." The only things each of the Disruptors ever cared for was Bron's "golden titties."
Is the correction just about the usage of the adjective "close" on my part? I mean, fair, but I don't see how that changes the absurdity of the fact that these people (the victim's girlfriend and his "pack", "friends", "group", etc.) who have been hanging out at the bar, shown drinking together and established knowing each other for years and years, somehow are oblivious to the violent allergy of this person - something Duke himself is not secretive about and that they know would kill him with just a drop. It's the typical unrealistic dumbing down/forgetfulness of whoever in a wuddunit is not the main character (hence a stupidity, never painted it as a plot hole).
I get it. You say it is stupid that a group of friends know each other so poorly. I'm saying they were never friends. They cared for their own benefits. Hence, they never sought to know each other, let alone care.
Plot hole: Benoit Blanc ruins on purpose the murder dinner party because, allegedly, someone is really trying to kill Miles, and he wants to warn him that it's not a game. But as we know later, Blanc is actually trying to investigate the murder of Andi Brand and he does not really think that Miles Bron is in danger. In fact he is positively convinced that everyone has motives to kill in order to protect Miles and all he wants to be on the island for is to gather clues and investigate. Cutting the game short does not serve his purpose at all, in fact it defeats it. Had he played along, both Helen and him would have had a perfect excuse to investigate. In fact it is a miracle that nobody went back to their rooms right away after that tense moment, instead of being busy with the opening investigation; you even see that they are groaning and complaining and want to leave. The movie explains away most of the other details but none about this.
Suggested correction: Blanc knew he couldn't hide Helen's identity for long. He said so at 1:15:15. His fear was justified when Duke discovered Helen's identity on the night of her arrival. In short, Blanc and Helen were on a clock.
Regardless of how little time they had left (Blanc estimated "another week", so the leak happens presumably earlier than he anticipated), ruining the dinner does not serve the purpose; gives "Andi" less time to search the rooms, which is what Blanc planned her to do.
If the game was allowed to proceed, Helen would have been forced to play along. Any behavior, other than playing along, would have been suspicious.
Stupidity: Of course, it's a movie with a heavy comedic tone and it's a rather cathartic scene, but still it's worth noting that Benoit Blanc had no way to know that making the whole HOUSE (full of glass shrapnel, too) explode wouldn't gravely injure or kill anyone. What a ruthless fellow.
Suggested correction: The scene at point 2:06:02 suggests the opposite. Blanc knew the house would explode violently, hoped everyone would get injured, and sat watching it while helping himself and Derol to a cigar. Bron was guilty of two counts of first-degree murder. The remainder were accessories to the crime, having already pledged to perjure themselves. Their sentence would be death if it were not for their destruction of evidence. So, all Blanc needed was a sense of justice, not ruthlessness.
Helen, the innocent sister of the original murder, is in the building too. I wouldn't want to say that he hoped *everyone* would get injured, just the bad guys but that's the point. It's simply a case of an absurd decision that puts to mortal risk everyone but has no negative consequences "because movie."
