20 TERRIBLE Horror Movies That Were Huge Hits

There was a considerable amount of goodwill going into M. Night Shyamalan's Glass, considering that it was a sequel to Shyamalan's acclaimed comeback Split, which was itself a secret follow-up to his 2000 superhero film Unbreakable.

Despite being hyped up as an epic conclusion to Shyamalan's genre-bending superhero horror-thriller franchise, Glass was a colossal disappointment, with particular regard to its frustratingly expectation-defying third act, despite committed performances from James McAvoy, Bruce Willis, and Samuel L. Jackson.

But Glass still absolutely cleaned up at the box office, where it grossed $247 million on an incredibly tight $20 million budget.

Collectively, Shyamalan's Unbreakable trilogy has grossed over $770 million on a combined budget of barely $100 million, and had the filmmaker not decided to close the franchise off with Glass' concrete, audience-alienating ending, he probably could've kept it going for another installment or two.

As Shyamalan's third straight box office success after the failure of 2013's After Earth, though, Glass confirmed that his name still carried weight with general audiences, no matter the wildly mixed quality of his filmography.
