I heartily agree

I love a good rom-com-zom-dram. (Romantic comedy zombie drama)

Shaun of the Dead covers that ground nicely.
- I'm not entirely sure why but I find Simon Pegg VERY attractive in this movie. He's like the perfect balance of heroic and vulnerable, doing his best in a bad situation.
Warm Bodies?
And I think Disney has a series of movies with zombies called something lame like Zombies, Zombies 2 etcetera
- Some of those songs from those movies are low-key bangers though

Too many Christmas movies period. Also, you notice how many movies there are about saving Christmas? No other holiday needs to be saved. When was the last time you saw a movie about somebody saving Easter or Thanksgiving?

Trains Planes and Automobiles is about Thanksgiving. Passion of the Christ is about creating Easter at least.
But yeah they're pretty thin on the ground, especially once you get past those two holidays.
- Now I want a movie about saving Easter set in bible times with Judas as the protagonist.
Hop (2011) from Illumination is exactly that formula but Easter. Also agreed very few outside of the insane number of Christmas ones.
Nightmare before Christmas is also unusual in being directly about saving Christmas but indirectly saving Halloween.
The Persecution Complex is built right in.
- It pairs nicely with the capitalist hunger for a shiny new toy

100% Agree. OK, here's my pitch, Netflix:

Lilith, a witch that lives in fast-paced New York, is also a passionate pumpkin carver. To harvest the best crop of mugwort she knows, she returns home to the town of Spooksville. As the autumn leaves turn, she meets Jake, the town's charming ghost tour guide, at the annual Haunted House contest. He helps her harvest the mugwort and she helps him remove a curse put on him by a crazy ex-GF. She decides to stay through Halloween to see the pumpkin carving competition. As they navigate spooky pranks and unexpected feelings, they uncover a magical pumpkin that grants wishes— and Lilith wishes that Jake would love her, but the pumpkin says "I cannot grant a wish that is already fulfilled!" It turns out the ex-GF curse was to harden his heart, so all he did was be terminally online posting AI slop on Twitter. They kiss and go make like 32 babies in some cracker-ass podunk town and listen to country music and whatever else is at the end of a Hallmark movie.

Love it. That second sentence needs a record scratch and switch to a higher tempo track. Make Rob Schneider a talking pumpkin and you've got yourself a winner!
- Let's make it a trio of celebrity voices as 3 magic pumpkins that have to agree on a wish to grant it: Rob Schneider, Hugh Grant, and Reese Witherspoon. Maybe Queen Latifah, if that counts as "diversity."
  Record scratch is that she needs 100% organic mugwort grown on a south-facing slope in well-draining soil. First small twist- turns out the perfect crop she needs is on Jake's back 40 and he finds her plucking mugwort leaves while driving around on a tractor harvesting his own sweaty abs in an open sleeveless orange and black snap-up plaid cowboy shirt.
  Really, someone give me $1 million and I can get this done!

Cuz Christmas is often associated with heartfelt Romance and Halloween is often associated with dirty monkey sex.

There are a large number of witchy (in both ascethic and main characters) books that are popular now. There is a whole genre which means that the witchy / halloween themed movies are coming.

A Night In The Lonesome October by Roger Zelazny.

A talking dog keeps a daily diary, starting October 1. There's going to be a full moon on Halloween, which means the barriers are going to be particularly permeable. Various mad scientists, witches, body snatchers, werewolves, detectives, and serial killers are gathering in a small English town for The Game...
