When youâre getting into horror, especially as a kid, itâs fun to learn the various weaknesses of the different movie monsters. After all, when youâre a child, all of those things hold an element of reality to them. You know theyâre not real, but you also want to be sure youâre prepared to deal with them should you ever have to. We learn the basics very early on. Vampires are afraid of a lot of things, from sunlight to stakes to garlic and religion. Werewolves, on the other hand, generally have one weakness: silver. Frankensteinâs monster is infamously afraid of fire. We all know these weaknesses. Impractical or not, theyâre classics.
From there, things just kind of got more convoluted, especially for the modern franchise monsters. Many of those movies were made by different people with different takes who wanted to do their own thing with these classic series. This leads to some contradictions, some which go overlooked, and some of which are almost impossible to miss.
And sometimes, be it sequel or not, there are killers with weaknesses that donât make any sense. Rules set for a specific kind of supernatural film that just leave you scratching your head.
Shooting Chucky in the heart in Childâs Play
As a kid, I thought this one was really cool. And itâs still really effective on film. The whole climax of Childâs Play is exciting and I was so scared of Chucky as a child that I thought it was great to have some means of defense in case the doll ever showed up on my doorstep. But when you think about it, it doesnât make any sense. Chuckyâs whole body is turning human, he discovers this when he gets shot in the shoulder and it bleeds. So the âhis heart is almost humanâ line kind of throws you for a loop, because technically shooting him anywhere else should have the same effect as shooting him in the heart.

OK, this one is actually a vampireâs lack of weakness thatâs pretty stupid. It counts because heâs being subjected to all of the things that normally weaken a vampire, and they donât work. Maxâs explanation is that inviting a vampire into your house ârenders you powerless.â Itâs a bunch of nonsense designed to hide the identity of the master vampire in plain sight for the bulk of the movie.
The Leprechaunâs gold
OK, gold doesnât weaken the Leprechaun, but it is his major weakness. Itâs all he wants in life. And itâs a motivation thatâs so easily solved it requires some heavy plot work to get a whole movie out of it. In the first film, one of the main characters accidentally swallows a coin in order to get more mileage out of the concept. The sequels had to come up with special abilities for the goldâlike its ability to grant wishesâto give people a reason to want to hold onto it even in the face of certain death.
The Voorhees family dagger in Jason Goes to Hell
I think Jason Goes to Hell gets a bad rap for being a sequel that wanted to try something new. Itâs a very different, overtly supernatural, possession-themed entry and I think for the most part it succeeds at being a gory and entertaining ride. But some of the Voorhees backstoryâand the way it ties to the plotâis questionable. Not only do we have the very Myers-esque idea that Jasonâs bloodlust is now tied to his own bloodline, but only a direct relative can actually kill him. And the only way a Voorhees can kill him is with a special dagger that definitely appears to be lifted off the set of The Evil Dead.
The Leprechaunâs fear of wrought iron in Leprechaun 2
Leprechaun 2 is a fun and often more successfully humorous movie than the first, but the Leprechaunâs one weakness is changed entirely. As absurd as the premise was from the beginning, the Leprechaunâs allergy to four-leaf clovers made sense with what they were trying to do. This is a little more random and basically makes the Leprechaun a hypochondriac whoâs very concerned about tetanus. It also makes him a little more easy to defeat, which is the opposite of what a sequel should do.
Samaraâs cursed VHS tape in The Ring
Samaraâs greatest strengthâthe fact that she is a cursed ghost tied to a videotapeâis also her greatest weakness. Itâs kind of baffling to me, in retrospect, that The Ring was released after the introduction of DVD. The whole premise was already outdated by the time this idea hit the US. First of all, with a bootleg VHS like that, thereâs no way it would be shown to that many people without eating itself from the inside out. Youâd have to constantly adjust the tracking, or pause it to take out the tape and make sure it was okay. And if you did pause it, why start it again? Why on earth would people watch the whole thing?
Jasonâs fear of water in Freddy vs. Jason
Friday the 13th, The Final Chapter, Jason Lives, The New Blood, Jason Takes Manhattan. These are all of the preceding movies in which Jason goes in the water of his own free will, presumably without a resulting panic attack. I donât need to get too far into what a terrible idea this was to begin with, because everyone already knows that. Fans have been complaining about it for a decade now, and with good reason. Anybody who had seen any of the entries before Freddy vs. Jason would know that Jason doesnât mind going in the water. Even in this one, there are several scenes that show him submerged or wading without a word of complaint.
