What is any movie without conflict, and by extension, what is any movie without a villain?
Though it's understandable that most films invest far more effort in developing their heroes, it can often be at the expense of delivering a compelling or well-rounded Big Bad.
Now, this isn't always a mistake, nor is it always bad storytelling. Sure, it can be the fault of a writer who just didn't care enough to give the hero an interesting villain to fight, but sometimes it's actually a narrative function that the antagonist takes a backseat to the protagonist.
And so whether for better or worse, these 10 movies all served up villains which almost immediately evaporated into the ether, remembered by practically nobody.
If someone showed you a single picture of these antagonists, you'd almost certainly struggle to name them, either due to how poorly they were written or how utterly insignificant they were in the scope of the movie itself.
While we all wish we could forget the terrible likes of Justice League's Steppenwolf (Ciaran Hinds) and Fantastic Four's Doctor Doom (Toby Kebbell), you'll probably develop a migraine trying to remember who these 10 villains were...
