Why are There a Kajillion Friday the 13th Movies and No One is Making Zombieland 2?

I am not a person who usually enjoys movies with a lot of gore.  I love being scared by a movie- Psycho still gives me the willies, and when that little girl's head twisted around in the Exorcist, my five friends and I slept with my Mom when we were thirteen- but brains and eyeballs popping is just gross.  I also like, enjoy, love bad movies, so I thought I had a no brainer when I watched Zombieland for the first time.  I have never been more wrong.
I quote that movie more than any other.  Especially if I see a clown (and anyone who has seen the movie knows what I say) or if I am killing a bug. (Rule # 2)
A sequel can be a wonderful thing-Rambo 2- or it can make you wonder if they even watched the same movie that you watched. (Too many to mention) But Zombieland is hilarious.  If they had brought on the original cast again, it would just be priceless.  Too bad they can't seem to get themselves coordinated.
I'm sure that leaves room for another Scary Movie sequel.  I enjoyed the original, let's stop now.
While I believe that Keenan Ivory Wayons is a directorial genius (I'm Gonna Get You Sucka) the whole premise of  Scary Movie just feels tired now.
Don't get me started on any movie with Jason or Freddy Krueger as a character.  How many ways are there to slice a person open.  For that matter, why hasn't the police done something about those mass murder areas just waiting for six to eight stupid, drunken teenagers to wander into?
Good movies are a treasure.  We need more of them.  We don't need any more sequels to things that stopped being funny six years ago.  Apolitical movies that are funny and can make you forget your troubles for awhile-even better.
So on the off chance that someone knows someone who has any say in the making of Zombieland 2, please tell them to get on it.  And if you haven't seen the Zombieland by all means go see it!  You'll thank me later.
