The 28 Days/Weeks/Years Later film series is fairly odd as far as franchises go. The first film was from a clearly an attempt at artistry despite being in a classic genre that COULD just be lowest common denominator genre fodder. They established an Alien-like quality where the films are gonna be different in regards to cast and tone and director with the sequel.
But then the franchise seemingly just died after two films due to rights issues. And then it became oddly hard to legally watch the first film unless you had the DVD? Now, all these years later, Danny Boyle and Alex Garland have a three-film plan with the first two films shot back to back?? In an age where all studies are desperate to mine IP, it was inevitable they would land back at this franchise. But its path to get there has been odd to say the least.
