I finally saw Sinister 2 and although I didn't think it was that bad. I think for some reason the people behind the movie did exactly the thing no one wanted to see for the sequel. Which is show and explain what was going on in the original movie. The quotes from the writer here:

explain the disastrous method of thinking behind Sinister 2 that pretty much destroyed the chance of a Sinister 3.
And who thought it was a good idea to add the husband character? I mean I know the reasoning behind it. But still, nothing in the original movie is so stupid like that.
