Modernize the 'Crimson Ghost'? What were they gonna do, give him an iPhone and a Twitter account? Good riddance to bad rubbish.
Oh wow, another character who's 'special' because they don't need sleep or food? Please. How about we write about characters who break the cycle by doing something actually meaningful? Like changing their habits or mindset? Not eating or sleeping is just... lazy writing imo.
Honestly, at this point, I think some dreams are better off in your head. Saves you the disappointment of reality. Got a drawer full of 'dream projects' that'll never see the light of day.
This sounds like it's been done to death in some form or other. But execution is everything. Maybe spice it up with an actual threat that challenges their sanctuary? Like an old rival hunter sniffing around or something.
What if? More like what a load of ifs. It burned, get over it. We would've prolly just used the knowledge to accelerate our self-destruction anyways. Humans, lol.
