The Gorge tried to emulate some of the visual aspects of Annihilation in terms of the colour pallette, but
spoiler
unlike the latter The Gorge completely neutralised the cosmic dread by trying to explain the horrors with pseudoscience. And it was baaad pseudoscience. Like the mutagen being "in the fog", which is gas coming from missiles (predating the V2 rockets??) that have been... belching it since the mid 40s?? Bullets and knives/sabres being alternatively ineffective and 100% deadly to the horrors, gas and affected creatures being magically contained to the gorge, him not being able to bring personal effects yes her having a record player and loudspeaker with her preferred music present, those "satellite cloaking signals"...
Plus, I dislike horror films where the protagonists survive in the end. It completely nullifies the dread.
I'd like to see 50-60 year olds doing up their hair like the Static-X guy.
