I believe that only a certain type of person could ever be hyped for Wishmaster. That isn't a knock on it at all, just a statement of fact.
No matter how this movie was marketed, it was only going to speak to a certain segment of movie goers. While there's definitely a non-genre audience that can get excited for the likes of, say, Misery or Bram Stoker's Dracula or whatever, Wishmaster is another matter.
Released in 1997, Wishmaster had '90s direct to video written all over it and yet was given a wide theatrical release. Anyone catching this trailer knew immediately whether it was for them or not.
