Horror fans see a movie like this as a challenge. It felt like if you watched Terrifier 2, you had conquered the arguably goriest movie ever made. This has led to the stomach-churning news that there will be a Terrifier 3 with an even bigger budget and even more gore.
It's also not particularly scary, although Art and his imaginary friend (it'll make sense when you see it) can be unsettling. The intensity comes from the gore, rather than any tense set pieces. If you've got the stomach for it, Terrifier 2 will be more of a treat than a trick for gorehounds this Halloween.
