Plot hole: After Max and Allison rescue Dani from the witches, Max is driving his parents' car. Winifred flies up along side of them and asks Max to show her his driver's permit. How would she know about driving permits, since she's been dead for 300 years?
Suggested correction: There is a lot the movie doesn't show us about who they've passed and what they heard all evening. One example being we don't know everything the bus driver said to them. It's perfectly reasonable they heard somebody make reference to a driver's permit and the movie did not show us this conversation deeming it invalid to the plot.
Not referring to a learner's permit. She would have known what it means. She's emulating a cop pulling him over. She would have to know what that means...and know the difference between a license and a learners permit. Enough to find it funny and relevant to the situation.
Plot hole: It seems unlikely that Debbie would have managed to take the photographs of her husbands' murders she shows the Addams family at the end, especially considering the angle of the shot of the surgeon. He's not looking at the cam so she wasn't holding it.
Plot hole: Towards the end of the movie we see Mr. Wilson peek out from his front porch, surprised to see Dennis biking back home with his wagon carrying Switchblade Sam, tied-up and partly unconscious. Either Dennis must have some hidden super-strength or knew how to tweak the laws of physics there is no way that an eight-year-old kid of his build could carry an adult of that size to his wagon let alone easily bike home with Switchblade Sam's weight. Plus being an experienced criminal like Switchblade Sam he may have offered some resistance in being caught doing so much less submit to a mere kid. (01:50:00)
