If you're just gonna take the 'vibe' of a property and tell a story 'set in the same universe', just create a new property.
The Resident Evil games are goofy, over the top, sometimes intentionally funny, sometimes unintentionally funny but also can be horrifying and frightening in equal measure. There's no reason why a faithful adaptation of a single RE story is impossible and, while I am excited to see Cregger's take because I loved Weapons, I am disappointed to see an adaptation of something I love in name only (supposedly).
I would sooner understand an argument that most RE game installments individually are too packed to fit in a single feature length film but throwing dirt on the franchise as somehow having a lesser story strikes me as confounding, especially give how lacking some of the story-lines in the most popular horror film franchises are.
