If you've never seen either of the Sinister movies stop reading this and go watch both of then come back. I'll even wait for you.
Okay if you just got back or have watched both movies already lets do this! Stop with the eye roll there are a hundred million reviews of both movies already I'm just discussing why I liked both and wish that they had made part 3.
I've read a couple reviews of the movies and complaints about both, but I'm not faulting any of them. I'm just typing about why I've watched them more than once or twice.
I think I'll start with the main reason that I'm disappointed that Scott Derrickson and C. Robert Cargill aren't writing or making part 3...
First I would have loved to have seen the summoning of Bughuul
by whoever had done it in Norway. And led to what was known as "The Norwegian Hell Call" with ham radio enthusiast in part 2.
Now without part 3 acting as a prequel as I would guess we would find out who discovered the music that opened the portal between Bughuul's realm and our own.
Dr. Stromberg had said that Bughuul exist in art and music and can enter our realm through either. So would that mean a musician had found some kind of sheet music that wasn't destroyed like others along with paintings and drawings?
And then this Norwegian musician had first played the music only to have his daughter exposed Bughuul's powers and influence. And then she turned on her father's ham radio to broadcast her song to Bughuul as carries out her sacrifice to him before being claimed by him.
Then the father of the family in the film pool party might have been a ham radio operator himself and accidentally found the Norwegian Hell Call. Then not only was Bughuul able to influence his son, he also found a new medium to exist in. And since it was in 1966 it might have had a influence on his appearance where he still had the Nordic hair and look, but decided to go with a suit of that time period to appear more normal to the kids he's influencing to do his sacrifice so he can deplete their soul after.
After that the camera and projector makes the rounds until it reached Ellison's family and Bughuul couldn't have asked for a better person to open the portal between realms. Ellison was so desperate for a second chance to hit the big time that having all of that information was too much to pass up. But by the time the danger of the reality caught up with him it was too late.
Then when (soon to be ex) Deputy So and So and Professor Jonas got word of Ellison's and his family's deaths as well as his daughter being missing they new that they had to take action.
Which would lead in to the events between parts one and two where Deputy So and So was let go from the sheriffs department and became a private investigator. And then began burning down all of the houses connected with the curse of Bughuul. And I think Professor Jonas planned to travel to Norway using the coordinates to find the original house maybe in the hopes of destroying that one. But I also think that Bughuul brought him to a nasty ending somehow before that had a chance to happen with the use of that ham radio Dr. Stromberg had in his lab at the university.
Now if you're saying there's no way Bughuul could have taken out Professor Jonas himself just think about the ham radio being in Ex Deputy So and So's hotel room before Bughuul appeared. Which means Dr. Stromberg met a bad end because he didn't get a chance to destroy the ham radio after Deputy So and So told him to.
