10 More Criminally Underrated Monster Movies You Need To See

10. C.H.U.D.

C.H.U.D. opens with a series of mysterious murders on the streets of New York City. Suspecting the killers live in underground, an eccentric group band together to uncover the truth. To their horror, they discover the government has been illegally dumping toxic waste in New York's sewers for years, transforming the homeless denizens into killer mutants.

Because the C.H.U.D. (Cannibalistic Humanoid Underground Dwellers) don't appear for over an hour, the film could be really boring. But due to stellar performances from John Heard and Daniel Stern (who starred together years later in Home Alone), viewers are left utterly captivated as they learn more about these creatures and the conspiracy behind what created them.

Even though the mutants' design is simple, it's highly effective. With their glowing eyes, melted faces, and pained expressions, you feel uncomfortable every time they're on-screen.

Although C.H.U.D. could've been a brainless B-movie, it has a surprisingly effective social commentary about how homeless are constantly mistreated and dehumanised. Because this message it still relevant in today's world, modern viewers still find themselves gravitating towards C.H.U.D., even after nearly 40 years.
