It takes place mostly in the dark, as if they're trying to hide that their slashed budget required they film in Bulgaria. I am not sure it would have helped to shed any light on it though. To say this series has gone far enough is pointless. They can keep going around in circles in the woods for the next 40 years and people will still find ways to put these films out.
All in all, it's a good and nearly great film. It's taken years for me to add it to my collection, though. I finally needed a somewhat safe movie for my kids to watch this Halloween, and that's really what we have here. I am sure they'll watch it in the future. Not sure if they'll ever know what the fuss was about. I think they will appreciate it, though.
