I don't watch horror films, so I'm really not best placed to give an informed opinion - but I'm happy to share my uninformed opinion.
I really enjoyed it. It has quite a bit of humor. I thought the premise was really good, and I can imagine if it was real, the audience watching live would have been terrified.
I might have the wrong idea of horror - I am of the impression it's supposed to be scary, but I didn't think it was. I tend to avoid horror because I thought that was the point - but maybe it's not? Or maybe I'm just too aware of the fact it's a film to find it scary. I don't know. I'll be interested in seeing what people that do watch horror think of it.
I would definitely recommend it, but my recommendation, given my lack of experience in the genre, might not mean much 😆
