The obvious for me. Friday the 13th. But sadly no horror franchise is perfect. And Friday the 13th still doesn't have an entry as good as the original Halloween. Which is a 10/10. Friday the 13th Part 6 would be the closest at around a low 8/10. I wish there was a Friday the 13th movie that was as good as the original Halloween or Nightmare on Elm Street. Or even the original or remake of Night of the Living Dead.

Dario Argento's Three Mothers Trilogy (Suspiria, Inferno and Mother Of Tears) and equally Lucio Fulci's Gates Of Hell trilogy ( City Of The Living Dead, The Beyond and The House By The Cemetary).

Wrong Turn (beyond the equal it gets shitty, but i still watch)
Scream

Saw with A Nightmare on Elm Street at a close second.

One year later, Halloween is still my franchise. But the battle for second place is always ongoing. Puppet Master, NOES, Subspecies, F13, Leprechaun are constantly fighting it out.

I'm waiting for someone to say the Vomit Gore trilogy.

Romeros original 3 zombie films
Nightmare On Elm Street
Halloween (all except Resurection which having rappers in it spoilt it totally 4 me)
Friday the 13th

Favorite franchises :
Halloween
Friday the 13th

Frame per frame, the Evil Dead franchise (incl. the remake) is the best. Although I enjoy the remake, I expected a bit more from it. Let's see whether the TV series maintains or tarnishes the whole and whether Bruce can make Ashley J. Williams a household name.

Wow, it's too difficult to pin it down to one type/name of a movie franchise so I am going to say zombies and vampires. I live for zombie books and movies, can't get enough of them!! Vampires.....what more is there is say??!!

I wish there were more werewolf movies out there. I enjoyed the Underworld series, An American Werewolf in London, Ginger Snaps series, and the Wolf Man. I would just like to see more modern versions.

I did see a movie poster for an upcoming vampire movie but I'm drawing a blank on the name of it. I hope it's good!!
