If other monster movies had 'blood relatives' like 10 Cloverfield Lane

10 Cloverfield Lane is the latest mystery box from man/magician JJ Abrams: a revolutionary new sort-of-sequel to his 2008 monster movie classic Cloverfield. He calls it a "blood relative" but what this means in real terms is "a sequel in all but name only". It's a technique that could catch on in the monster genre - spin-offs that springboard off an iconic monster attack but focus on something way less spectacular (and way cheaper to create). We humbly present the next 10 revolutionary new sort-of sequels to monster movie classics. That's right, JJ. We've bust your mystery box wide open.
