It seems like one of the hardest things to get out of Hollywood or an indie producer is a decent horror movie. "Satanic" is yet another in a long line of below par, forgettable horror movies made in the past 10 years. But at least it's not another crappy found footage film.
The production values on this movie are pretty good... again, no shaky, hokey found footage documentary-style garbage. Sound editing is pretty solid. The movie poster is ridiculous, but the movie looks and sounds pretty good.
But the story is weak... the story that picks up with Alice in the hotel makes no sense, and there's not much attempt to explain any of it. And these characters are awful. From the start, the four travelers come across as a bunch of self-absorbed, arrogant jerks. Seth the "goth" guy is particularly punchable. David and Elise are okay, but the former is pretty unbearable at the start. The tighten up a bit and get better as the trouble starts hitting them, but by that point I really had lost all interest in them. Some people have mentioned Sarah Hyland as being a star of some sort, but I've never heard of her or seen her show, and in this movie she's just your average "good girl" that you get in a horror movie... ends up being the Scream Queen. But she's not all that impressive... more irritating towards the end than anything else, really.
And the ending... meh.
If you don't expect much from your horror movies and are a very generous sort, it's possible you could give this a 4, I suppose. I was originally going to give this a 1, but that's not fair given the number of staggeringly awful horror films out there (like "American Poltergeist", "Ouija Experiment 2", etc).
