Very nice work It looks to me as if it represents horror archetypes. Monster, Demonic, Vampire, Ghost, Werewolf. All that is missing is Mummy, Unstoppable killer, Serial Killer, and Zombie. If you do intend to do more, might I suggest Michael Myers for unstoppable killer, and Hannibal Lector for serial killer?
Frankenstein is a zombie. "The Zombie" infact. The mummy is as well a zombie, who is just wrapped up in toilet paper. Except the ghost, all of these are monsters. The only archetype missing is the psychotic serial killer.
Frankenstein's "monster" is both alive and intelligent in the original story and in any movie that is remotely faithful to it. Mummys are ancient dead brought back to life by a curse enabling them to seek revenge on those who disturb them.
Zombies are mindless undead or infected living creatures whose sole motivations are to rip apart and/or eat any other living thing, preferably humans. Neither Adam (Frankenstein's monster), nor Mummys fit that category in any way.
Additionally, I think very few horror afficianados would lump vampire movies in with Hellraiser, or Werewolf movies. They are quite different categories. Just because something isn't human or is demi-human doesn't automatically qualify it under the heading monster. You might argue Werewolves qualify as monster, but that's about as far as your argument has legs, unless you are using monster in very broad psychological terms indicating beings with motivations different from the average human, in which case serial killers would also qualify.
"Monster" is a generic term for lifing things that are unnatural and mostly scary. It does not differ between good or evil, nor the degree of deformation. In oldern times even cripples were called monsters. Today there are a lot of creatures we call monsters, but all of them belong to a certain categorie of monsters, wich we are mostly to lazy to learn. You can look them all up, if you want.
Zombie is also a lot wider as what you describe. It just means "living corpse". It does not specify whether the corpse is intelligent or not, nor what it likes for diner, nor how it was brought back. 99,9 % of the typical mummys even act like zombies. So with enough time and bandages I could turn my army of zombies into mummys and noone would notice. Also Necromancer usualy use curses to bring back the dead. So were is the difference, expect for the ten layers of toilet paper?
You are propaly right, when you say, that the original Frankensteins monster is not a zombie since its never specified, what he is made of. But his later incarnations are mostly described as parts of corpses taped together. These would count as zombies.
I read the book in high school for a book report. The part near the end where Frankenstein realizes the monster is watching him through the window scared the shit out of me. I've had a sort of window phobia ever since I saw the episode of The Twilight Zone with the gremlin on the wing of the plane as a kid.
