They are:
- Godzilla Minus One (Takashi Yamazaki, 2023)
- The Host (Bong Joon-ho, 2006)
- The Descent (Neil Marshall, 2005)
- Pan’s Labyrinth (Guillermo del Toro, 2006)
- The Mist (Frank Darabont, 2007)
- A Quiet Place (John Krasinski, 2018)
- Trollhunter (André Øvredal, 2010)
- Cloverfield (Matt Reeves, 2008)
- Prey (Dan Trachtenberg, 2022)
- Attack the Block (Joe Cornish, 2011)
Good shout - I’d put Nope and Hellboy (2004) on there. Also definitely Slither (2006) and probably Grabbers (2012) and Feast (2005).
I don’t think Monsters (2010) would quite make the cut but would sneak into the top 20.
