'Terrifier' is a mixed bag.
The gory stuff is done to a decent degree, even if those moments are a bit too few and far between. Art the Clown certainly looks and acts the part, even if I wanted more from the character - giving him a voice would've made him more creepy in my opinion, rather than complete silence.
This 2016 flick was made on a tiny budget, something that is very evident throughout, but given that you do have to hold appreciation for the filmmakers. I will say, though, that the level of acting is iffy and the dialogue is rather terrible, at least for the most part. The former is understandable given the aforementioned, though the latter is a negative.
I am anticipating better from 'Terrifier 2' and 'Terrifier 3', given the presumption of a larger budget and all that comes with that. I still respect this original attempt, but I personally wouldn't class it as anything that is strongly worth watching.
