Plot hole: A core plot point (lifted by the comics) is that Venom needs phenethylamine, and the only way to get it is from brains and from chocolate. Let's just go with it and forget the fact that phenethylamine can be legally purchased as dietary supplement, which would solve every problem. So, Venom gets incredibly angry because Mrs. Chen's shop ran out of chocolates, and *therefore* they need to go raid a chicken plant to eat some chicken brain. Uh, Venom lives in San Francisco. Chocolate is sold everywhere. If Mrs. Chen ran out of it, there are hundreds of stores and vending machines that have it in abundance. The escalation does not make sense.
Plot hole: It is of course possible that Eddie Brock heard nothing at all about the biggest news in the whole city and State if he did not turn the TV, check the phone or computer for about 24 hours. But there has been a manhunt for Kasady for that long of a time and nobody including the police checked on the one man Kasady is trying to kill, and who was chilling at home all along. Also, obviously the "breaking news" moment is not breaking nor news. (00:40:25)
Plot hole: Venom has a photographic memory; he reproduces Kasady's sketch, an outline that matches perfectly a result (already on screen) of the google image-y search page for Rodeo Beach, California. Sure, it's a movie, but this plot device straight from Rise of Skywalker means that Kasady also had to have a photographic memory and that someone took a photo exactly from that one precise spot that happens to be also the exact one that showed up in "WebFindit." A couple of coincidences too many. (00:11:10)
