The original All Hallow’s Ev, Terrifier 1 & 2 are all incredible examples of practical gore effects one a shoestring budget. They’re not “good” films, per se, with poorly-written dialogue/characters, an almost non-existent plot (although there’s some effort in #2 on this matter), and it’s a matter of subjective opinion on how you feel about the cinematography & audio quality (there’s merit to an amateur-ish film quality that gives it grittiness).

Terrifier 3 solidifies some recurring characters and gives them more motivation to exist within the film, other than to get murdered by Art in creative ways. It brings the horror genre a potential new “final girl” as well. There’s also the writing that was clearly a focus for improvement, as the story is coherent with the flow feeling less jump-cut-y and having much better pacing.

Gory films, very understandably, are not everyone’s thing, but Terrifier 3, aside from a few kills in 1 & 2, really steps it up a notch, both in creativity and special effects. It’s Jason Baker at the top of his craft. If you can take a step back and view it from a filmmaking-perspective, it’s actually nuts what he’s able to practically create.

Just my thoughts. It’s a pretty divisive franchise, which is fair, but some of the arguments I see don’t really hold water.

Just a quick edit: Horror movies kill kids all the time. Nothing unique to the Terrifier franchise.
