I am a fan of Adams family. I have watched both "The Deeper You Dig" and "Hellbender". Good movies, especially Hellbender, by those talented artists who obviously love a lot the horror genre, and they try to leave their mark on it. I respect their effort, with the means they have at their disposal. These are not groundbreaking movies though, neither great ones. Their movies are not scary neither much intense. For example, HELLBENDER is something like a "Coming of age/indie/art horror". It's easy to make a garbage movie like every other horror movie nowadays, with masked killers or demons killing everyone, but this is just a copy of a copy of a copy. Adams' movies have identity and their movies are kinda unique.
That doesn't mean they're very good. And "Hell hole" is my least favorite movie of them. Of course it's not scary as expected but at the same time, it's not much intense neither interesting. Keep in mind though, this is more comedy than horror. At least, i saw it that way. And when i understood what this is about, i had a lot of fun, there were even some hilarious scenes during the last 20 minutes.
So, it's important to lower your expectations and undestand what this is about. If you expect something as i described it, you will find this movie entertaining as well.
In any case, this is definitely not a MUST WATCH movie and i expect something better in the future. HELL HOLE is not a failure imo but neither a step forward by those film makers.
