This is a personal opinion, so take with a grain of salt. I don't watch a lot of horror films, since they are either riddled with cheap jump scares, or very poorly made, but Hereditary was amazing. I'm not saying it was perfect; there were questionable plot points, and there were a few elements that could have been made better, but the atmosphere was superb! The plot is consistent, and its slow burn made it all the more terrifying. So, if you're looking for a good horror flick, this is it!
