This movie, to put it simply, fails as a horror. Miserably at that. However, if you go into it expecting not something to scare you but instead a comedy, then it's actually a pretty enjoyable experience. I'd recommend bringing some friends along as laughing at it with others is just too funny an opportunity to pass on.
The actors do a decent job. They're not going to shock you with their performance (aside of the decisions their characters make during the movie, because at that point, I think it's just natural selection rather than a streak of unluckiness) but it's definitely not terrible.
The scares are nonexistent. I doubt a child would get scared much at the movie, let alone an adult! But what they lack in scary content they make up for with the utter nonsensical writing; the characters' actions will have you yelling at them to do what any normal person would, because they're kind of stupid.
Overall, this movie doesn't deserve a high rating because it's objectively not good. But even if I rated it a low score, I think it's still enjoyable if you watch it in the way I mentioned before - like a comedy, not a thriller/horror.
