I think we need to resign ourselves to the inevitable fate of repeat/rebooted houses. Why?
Because our houses are based on movies...or to a lesser extent TV shows. What has been rebooted in the last 20ish years? This is off the top of my head but feel like they've all been done in the 2000's. Texas Chainsaw Massacre, Friday the 13th, A Nightmare on Elm St, The Thing, Poltergeist, Childs Play, Chucky TV Series, Halloween twice (Zombie and 2018), Ash vs Evil Dead Series, From Dusk Till Dawn Series, etc that have all had houses. Add to it long term sequels that have nothing to do / so far removed timewise from the "proper" franchises that have already appeared; Aliens TV series, Prey/Predator, Dr Sleep, Evil Dead Lives, Exorcist, Ghostbusters, forever in development Beetlejuice sequel rumored to be coming, etc. Then add in the stuff that hasn't yet appeared at HHN like Hellraiser, Candyman, It, Scream MTV version, etc, etc, etc. They've all been re-imagined/rebooted.
The fact that the horror genre, that should be infinite in it's possibilities, keeps on re-doing itself has to be reflected in the pool of IP houses that HHN gets. I think the fact we're getting returns of houses that have been "rebooted" in the films makes sense. The public has spoken and for every new original like M3gan that succeeds, there are 20 horror movies that fail or don't even get picked up for wide distribution. Shudder might be making great content, but make no mistakes about it, they have VERY few subsribers and if their content tested high enough to warrent a theatrical release, they'd certainly do so. People will show up in droves for the new Halloween, Nightmare, Friday, Scream, whatever movie...so why wouldn't those same IPs continue showing up at the world's premier horror event?
Then look at movies in general, the top 20 movies each year consist of 15+ sequels, ~8 of which are comicbook movies. People speak with their wallets and what they want is what they know and feel comfortable with. Think we need to have realistic expectations about that reality.
