For a perfect rate I would have put down 5.5 stars, cause 6 is too much and 5 still too little, but, we have to work with what we have, so 5 stars from me and one positive review!
Without spoiling it or give away unnecessary information, I'm going to keep it short and let you know, that Demonic, even tho such a cliché of a name, plot and even cover, stands up much better than most such productions probably because it was kept simple. Effective, intriguing, good acting, well picked actors, it wasn't the "let's do a horror in the woods" or "in a haunted house", but I genuinely think they wanted to make a horror. And they sure succeed!
So, compared to a lot of similar movies, Demonic offers thrills, scares, a little bit of mystery, overall, a good time!
Cheers!
